Use the upg icon

[DexterFstone]

Hi everyone. I had a question, I wanted to know what the use of the upg icon is and how I can use it. For example, should I enter the number method? (Charging example)

UPG icons are used for the rank of upgradeable spell caster units (e.g. Priest, Necromancer, Shaman). The "Art - Caster Upgrade Art" field determines which caster upgrade icon is displayed on the bottom middle part of the screen, below the unit's name.
