This page lists all known Immunities in Dungeon Boss, grouped in categories. For convenience, an Immunity can be in more than one category and is listed multiple times then.
Note: The immunities listed here are an effect of various Traits that often share the same name. If you're looking for Debuff immunity, check out Effects/Buff and see the Status Effect category. There are buffs listed, such as Shrouded, that temporarily grant immunity to various Debuffs.
In Dungeon Boss there are a few Resistances that increase the chance to resist debuffs and reduce damage of that kind.
