Auxiliary Abilities are special side abilities in Purgatorio that give your character extra combat effects, buffs, debuffs, and survival tools. They are not your main attacks, but they can make a big difference during enemy waves.
You can get auxiliary abilities mainly from two sources: wave upgrades and augments. Some abilities are selected while clearing enemy waves, while others come from specific body augments.
