This page shows every Expert Hero along with the total resources needed to fully max them out — including Sigils, Affinity XP, Books of Knowledge, and Skill XP. Use it to see the big picture before you commit to a hero.

Sigils are the currency you spend to level up a hero's relationship. You earn them through events and in-game activities. The higher the relationship level, the more Sigils it takes.

Books of Knowledge are used to upgrade a hero's skills. Each hero has different skills and costs, so the total you need varies from hero to hero.

Use the Relationship Calculator for Affinity and Sigils, or the Skill Calculator for Books and Skill XP. Both are linked at the top of this page.
