In Octopath Traveler 2, you will want to take your characters to their respective primary job altar to unlock an EX Skill for them, a very powerful and useful skill unique to that character.
Only primary jobs can learn EX Skills. This means that only Throné can learn Thief EX Skills, and you’ll need to take her to the Altar of the Prince of Thieves to learn it. You have to have the respective character in your party to learn the skill and secondary jobs cannot learn these skills at all.
All characters have two EX Skills, but they can only learn their second one after completing their story.
You can find most of these altars in the level 30 areas nearby where that respective job started, if you’re carefully looking at the minimap as you run about. The altar icon is depicted with several pillars over a rounded bottom line, so if you see that on the minimap, you can head towards it until you find the altar entrance.
Some altar entrances are in plain sight, whereas others are hidden under bridges or hard-to-see passageways. Below we show where to find all eight job altars in Octopath Traveler 2.
