Once you have a pet in Iron Soul: Dungeon, you can upgrade it through the Enhance and Ascend systems.
How to upgrade your pet
- Enhance — boosts your pet's base stats.
- Ascend — a larger upgrade tier that unlocks after Enhance levels.
Both are how you make your pet stronger for expeditions and equipment enhancement.
How to access it
Pet upgrading is part of the Enhance equipment quest line — look for Cinder to get started if you haven't unlocked it yet.
