Revision 1

Adventurer Power increases through Keepsake upgrades and ascension, stronger weapons and armor, Engravings, leveled Visages, and the equipped Buddy.

Keepsakes raise character attributes. Engravings enhance skills and passives and consume Zenny, Engraved Gems, and Resonance Crystals.

Visages add variable stats. Buddy progression also contributes to the equipped Adventurer's power.

Proof of Mastery can require a minimum power on at least one Adventurer. Ecological Rank and story progress may gate the next equipment tier or level cap.
