Octopath Traveller is quite a big game and with some of the mechanics falling back to the old JRPG days, it's not an easy game either so here are some tips that should help you.
After clearing the first chapters, you might notice shrines as you explore Orsterra. These will allow you to unlock jobs as sub-jobs for characters which will make them much more useful such as Ophelia a cleric being able to use black magic instead of just white and boost their overall stats such as max HP. You can also mix and match any support skills from different jobs as long as you've unlocked them.
You don't actually have to fight anything. Just go in and obtain an artifact. Not all are so obvious and show on the world map so here's a list of them although if you're in the right area, you'll notice a shrine icon appearing as a waypoint.
|Merchant||Moonstruck Coast north of Stonegard.|
|Huntress||East Victors Hollow Trail.|
|Apothecary||East Saintsbridge Traverse.|
|Cleric||Western Stillsnow Wilds|
|Dancer||Northern Wellspring Sands|
|Scholar||Western Noblecourt Flats|
|Warrior||North Stonegard Pass|
|Thief||South Quarrycrest Pass|
These powerful jobs will require you to defeat a boss and recommends you're at least level 50 before attempting them.
I didn't have too much of a problem with my party at around level 52 with the exception of Warmaster which was a DPS race during the last phase. I didn't have Cyrus the scholar levelled to boost my DPS high enough to finish the boss before she unleashed a huge chain of attacks so it wasn't until I unlocked Starseer and Sorcerer that I managed to win.
Overhealing by equipping your party members with the cleric's "Saving Grace" support skill will help so that you have more HP than whatever's your max HP.
North Riverford Traverse. Riverford can be found southwest of Quarrycrest.
Western Wispermill Flats. This is a little trickier to spot. As soon as you exit Wispermill there is a path between the red flag and cows you can go into.
West Everhold Pass just near the save point there's a chest and to the right of it there's a path obstructed by rocks you can follow.
East Duskbarrow Trail
Farming "Leaves" Money
Money has never been a problem in Final Fantasy or even the more recent Bravely games. However, you'd probably find yourself struggling here early in the game even if you thoroughly go about exploring dungeons to hunt down all the treasure.
What you can do is if you recruit Tressa and also Cyrus then unlock his "Evasive Maneuvers" skill, you can run around near the entrance of high level dungeons which will let her gather money from "unfortunate souls". The longer you walk/run around before you leave the area, the more money you'll get. e.g. At level 20 I visited a level 43 area and got 2K in less than 1 minute just doing this. Zoning between level 50 and 47 areas you can make 30K in 5 mins or so.
It's boring but it feels like the quickest way to make money. I found a good way of tracking how long you've been running around for is to remember what part of the background music is playing. You may also want to unlock Ophilia's "Evil Ward" so that if you ever end up encountering the enemy you have a chance to escape.
Whatever way you choose, once you've finished one character's story you shouldn't have money problems any more since you can almost breeze your way through the other chapters and save money that way.
It's back to the level grinding of old JRPGs. Even Bravely you didn't have to grind this much. So, that means you find spots where you can wipe out an entire group of enemies instantly with a single AoE attack. If you're lucky, you just might encounter a Cait Sith carrying a rucksack while running around the fields. He appears about once in every 30 battles.
You can also try your luck with Primrose's "Bewildering Grace (BG)" dance while you're grinding which gives a random good or bad effect. Most of the time it will be bad such as a debuff, ailment status or leaving your entire party with 1 HP leaving them vulnerable to the enemy...
Some of the good effects are XP/JP multipliers 2x, 5x or even 100x. If you're really, really, really lucky you might even get 100x XP bonus and summon Caith Sith at the same time. At that point you'll need to use magic spells to hit him. Physical attacks will always miss. And yes, the multipliers can stack too. You can roll 2x XP twice if you boost first and end up with 4x XP! I managed to get the 100x multiplier twice towards the mid-game during level 50s and got 70K worth of XP in one battle.
However, I wouldn't try too many times. Just save up BP (having a merchant helps) and use the skill once with as much BP as you got. If you get the multiplier great! If not, just finish off the battle and try again the next time.
Just be sure to save often if you use multiple BP with the skill because you can get hit with a 1 HP attack and then get wiped with an explosion... Yay!
There are also two accessories you can obtain to ease the grinding.
First the "Captain's Badge" which is a quest after you finish Ophelia and Olberic's stories. Find Bale in Wellspring and speak to him twice to get the "Back With Bale" quest. Go to Goldshore Cathedral to scrutinise/inquire Bishop Donovan then return to report and you'll have the a 1.5x XP multiplying accessory.
Next is the "Badge of Friendship" which will require you finished Ophelia's story. Go to Saintsbridge: Upstream to speak with Emil, the little boy to get the "Friends Again" quest. Find the bully back in the main area just off the bridge and buy/steal the River Blossoms off him then return and give it to their friend Nate. You'll now have a 1.5x JP accessory.
Once you hit the level 50s you will probably have or should be unlocking the advanced jobs. Warmaster's "Extra Experience" and Starseer's "Hard Worker" support skills will give you extra XP and JP too which stacks with the accessories mentioned above!
You can visit Forest of Purgation west of Wispermill where an enemy called Chubby Cait can often appear and just like Cait Sith, only magic can hit him and defeating him can give you lots of XP/JP. About 3K XP and 1.6K JP without multipliers. If you equip the Forbidden Bow and Alluring Ribbon you can increase enemy encounter rates to speed things up too. Just don't forget to remove the Evasive Maneuvers skill.
Revenants are rare but if you do come across them in the forest be sure to finish them off quickly. They have around 17K HP and they can be deadly after they use Overclock to buff themselves up. If you have the opportunity, you can also steal Revitalising Jam off them - an extremely rare item you can't buy that fully recovers HP, SP and BP. You'll probably need it later if you plan to take on the secret dungeon.
By mid 60s you'll want to have a mage such as Cyrus, Ophelia or Primrose with Sorcerer subbed and equip them with the support skills Boost Start (Starseer), Patience (Hunter) so that you'll mostly get the first hit. Then you can do a proper level grind and finish battles almost as quickly as you started. I stuck with Primrose because she seems to be the speediest and mostly gets the first hit. Only the Sorcerer should have Patience, no one else. SP Saver (Merchant) is optional or you'll be using lots of Inspiriting Plums to restore SP.
Bump up your elemental attack as high as possible with the right gear and Sorcerer's support skills so you can end the battles quickly in one turn and it won't be worth using BG any more. Breaks will give you bonus XP. However, if your dancer gets their turn before the sorcerer or you happen to encounter a Chubby Cait and manage to defeat it first, you can try using BG a few times to get a multiplier to bump up the XP. Otherwise, don't bother and just opt to speed through battles instead.
Other members can have skills such as Heighten Senses (Hunter), Grows on Trees (Merchant) and Intimidation (Sorcerer) to weaken enemies and save leaves while grinding.
Guiding, Alluring, Purchasing and Stealing Made Easier
Ever wondered if there's a way to increase the success rate for the story path skills?
Well, levelling up works but it only increases your success rate by tiny percentages. You actually have to make use of the inquire and scrutinise skills to talk to NPCs in various places to increase your chances. Catch is some of these NPCs are usually behind a "guard" so you'll also have to provoke/challenge. If you choose provoke, you need some powerful tamed monsters to win the fight so it's probably easier challenging - especially with warmaster subbed and you have Winnehild's Battle Cry skill.
You'll notice that if you fail you can lose reputation and then have to pay a fee at the pub to reset it before any NPCs will talk to you again. However, you can avoid this if you use the correct skills. For example if you use H'aanit's Provoke, you risk a reputation drop but if you use Olberic's Challenge instead, you won't. Alfyn's Inquire also has no risks compared to Cyrus' Scrutinise (no success rate either!).
Either way, both will require either party member to be levelled high enough before you can gain the following bits of info. Smarter Bartering will let you purchase items off NPCs much cheaper.

If you're missing good weapons and tired of farming for money, here are some that are free and fairly easy to get access to. You'll need Therion to open up the purple locked chests and with the Evade Manuever, Evil Ward abilities you should be able to walk in and take these.
There's quite a lot of good gear you can buy after finishing each character's story too. You will have to buy using Tressa's Purchase ability and if you're lucky, she'll sometimes haggle so that you get the items at a cheaper price. Or, if Therion's support skill is high enough you could steal for free although some really rare powerful gear you will just have to buy.

Secret Dungeon - Gate of Finis
If you've been paying attention to the stories you must have heard the name several times by now. As usual with SE games, there's another optional dungeon for those up for a challenge. Even if you're not you might want to try it anyway because there's a bit of post story in it for each character (or just watch YouTube I guess...). The final boss is very hard but the good news is, you don't have to defeat him to enjoy the post story.
To unlock this dungeon you must complete all character stories and complete the following chain of side quests.
|Daughter of Darkness I & II||
Go to Bolderfall, Ravus Manor Gate. Guess who the daughter of darkness is? Speak to Alphas the guard (strength 5) and challenge/provoke him. Once you defeat him you'll get Lyblac's attention.
|Kit, The Traveler||Chances are you might have completed this quest already.
Remember the starting location for your main starting character? Well, you might have come across a blonde, long-haired character named "Kit" and if you already gave him a grape then you'll have already completed this quest. Check your journal to see if you have and if not, here is a list of the starting towns.
Ophelia - Flamesgrace, Northern Flamesgrace Wilds
Cyrus - Atlasdam, East Atlasdam Flats
Tressa - Rippletide, East Rippletide Coast
Olberic - Cobbleston, South Cobbleston Gap
Primrose - Sunshade, Southern Sunshade Sands
Alfyn - Clearbrook, West Clearbrook Traverse
Therion - Bolderfall, South Bolderfall Pass
H'annit - S'warkii
|In Search of Father I & II||
After completing "Kit, The Traveler" above, head to Noblecourt to find him by the bridge and get the quest.
Now travel to S'warkii and make your way to West S'warkii Woods where you'll find Impresario near the save point. Talk to him, defeat the boss Azure-Eyed Tiger then talk to him again. You'll now be able to travel to Ruins of Hornburg which is to the south of Osterra.
This dungeon is a one way trip and there are no save points inside. Once you enter you won't be able to freely teleport back out either so be well prepared! It's a long run that will take an hour at least to beat but luckily we can set the Switch on standby any time we want of course.
Some people manage to beat this around late level 50s but, it would be best if you equipped your characters well and levelled them all to around 70. Stock up well on items too and maybe bring decent NPCs along to support you.
If you win, be sure to save in a seperate file if you want to fight the secret boss again because the dungeon will be sealed off afterwards.
...Or if you want to find out what to lookout for during the fight, read on.
First you'll have to fight tougher versions of 8 past bosses which are mostly from the characters stories at your own pace. Once you've defeated them you'll be forced to split up your 8 characters into 2 parties which is why I suggested having all characters levelled.
Setup was the following for me.
|Therion||Thief / Apothecary||
Physical Prowess (Warmaster)
|H'aanit||Hunter / Warrior||BP Eater (Starseer)
Surpassing Power (Warrior)
|Ophelia||Cleric / Scholar||Elemental Edge
Divine Aura (Starseer)
|Cyrus||Scholar / Sorcerer||Elemental Edge
|Olberic||Warrior / Warmaster||Physical Prowess
Saving Grace (Cleric)
|Tressa||Merchant / Runelord||Patience
|Primrose||Dancer / Cleric||Elemental Edge (Runelord)
|Alfyn||Apothecary / Starseer||Saving Grace
Don't use optimise for assigning gear because it will probably get it wrong. Do the usual, assign gear manually and bump up the elemental attack stats as high as you can for mages and give them some HP accessory. Melee jobs should have their physical attacks bumped up.
The apothecaries Alfyn and Therion have a very important role in this fight. They should have the support skill Patience (Hunter) so that they can skip the queue to do the following when needed:
- Use Energizing Pomegranates on Alyn and Therion when needed to fill up their BP so they can use the apothecary's Divine skill "Dohter's Charity" so items affect all members.
- Keep Dohter's Charity active and save at least 3 BP to use it again when the effect is nullified.
- Use Energizing Pomegranates, Refreshing Jam, Revitalising Jam when needed.
The idea is to keep BP high so that your party members can unleash as much damage in as short a time as possible or perform breaks. If you keep your eye on buff resets and keep the stacks up, you should be fine.
Now's the time not to hold back so you might as well spend all those permanent stat boosting nuts on characters who need them if you haven't already.
For this strategy I used around 4 Refreshing Jams and 6 Revitalising Jams so hopefully you haven't used them all up. You should have saved up quite a few from chests if you explored dungeons thoroughly enough. Otherwise, you can steal some Revitalising Jam from bosses such as the Heavenwing inside Carrion Caves (South Bolderfall Pass), Dreadwolf in Maw of the Ice Dragon (Southern Northreach Wilds) or rare enemies such as the Revenants that appear in Forest of Purgation. They can also be bought/stolen from NPCs such as Olneo the merchant (Rippletide).
Tough part about this fight is killing all the Souls at the same turn before it's the eye's turn which will respawn them all again. And, if you don't break/kill them fast enough you're going to be hit with some nasty debuffs and ailments. The nastiest one is probably the poison and the green aura that not just drains your HP but also your BP and SP too.
Have Ophelia keep "Aelfric's Ausprices" on Cyrus by stacking the divine skill so that he can always double cast his spells. The first soul is easy enough with light weakness. For the second group of two, have H'aanit break the top soul with bow attacks while Cyrus uses wind/ice spells. H'aanit can use her divine skill "Draefendi's Rage" to deal some higher damage afterwards.
As mentioned above, Therion's role is mainly to keep using the divine skill "Dohter's Charity" so he can keep everyone's BP/SP replenished but should also help break the eye with axe attacks.
Once the eye's alone it's your opportunity to deal as much damage as possible. Lower its elemental defence with Cyrus' "Elemental Break" and break it using axe attacks with H'aanit and Therion. Then Cyrus can keep hitting it with light spells while Ophelia can alternate between keeping Ausprices up, using light spells or staff attacks for breaking. Therion can help keep BP filled to bump up skill damage with Cyrus being the main damage dealer.
The eye's weaknesses are dagger, axe, staff, lightning and light.
The three souls is a bit trickier because every time you hit them, their weakness changes. However, instead of trying to hit them until the weaknesses match, exploit their weakness one after the other. i.e. target the first soul's weakness first, then the second, then the third and you'll break them all while dealing damage. With Ausprices in effect, you'll defeat all three before the eye can revive them.
Eventually it will respawn the three Souls again with the same weaknesses but numbers will appear above your party members. If you don't destroy them in time and the counter reaches zero, the party member will get KOed but if you've been keeping the divine skills stacked, you shouldn't have a problem wiping them out in time. Keep BP/SP filled, keep breaking the eye and hit them with your best area attacks. At this point, the eye is no longer protected by the souls so just let Cyrus use light spells to break and exploit its weakness.
If your DPS isn't high enough then the eye will replenish HP by devouring the souls. Then he will start using petrification so hopefully you still have the "Herb-of-Grace Potions" from H'aanit's story.
This fight can be quite nasty but tactics don't change too much.
Main difference is Tressa should cast Transfer Rune followed by Light Rune to increase and exploit weaknesses. Afterwards you should use her merchant skill Sidestep while Transfer Rune is still in effect and it will help the entire party evade physical attacks. This can be stacked up.
Alfyn should reserve BP to keep Charity up and replenish everyone's BP while Olberic will keep using divine skill "Winnehild's Battle Cry".
You will want to destroy parts in the following order...
- Abyssal Maw - Sword
- Blade of The Fallen - Ice / Lightning / Wind
- Lyblac - Sword, light.
Once only Galdera's left you'll have to wait until his veil of darkness disappears before you can damage him so, you can use this opportunity to replenish BP and stack up Sidestep on party members. It's important you keep everyone's BP up and keep breaking Galdera because he can speed up fast and start using "Exterminate" which can KO two of your members in a single turn. Sidestep will help your party survive the attack.
His weaknesses are lance, dagger, bow, ice and light so Olberic, Primrose and Tressa can hit him with regular dagger/lance attacks to break when needed. Otherwise Olberic can use Battle Cry.
As I mentioned earlier, be sure to save in a seperate file if you want to fight him again. Would have been nice if SE let you skip the 8 bosses and re-challenge Galdera after you beat him. Not sure if the intention was to discourage players from trying to perform a speed fight.
I was also hoping for some extra rare almighty piece of gear as a reward but, you just get a Spurning Ribbon that disables all enemy encounters but oh well... Have fun!
