Evilities are passive abilities introduced in Disgaea 3: Absence of Justice. The name is a portmanteau of "Evil Ability". Each character comes with a Unique Evility that cannot be unequipped, but they can freely equip others besides that.
Each class learns their own set of Evilities, with Unique Characters unlocking them Evilities by leveling up while Generic Characters unlock them as they reach higher Class Tiers. Once unlocked, the new Evilities must be purchased with Mana at the Evility Shop. The shop also sells an array of generic Evilities on top of the character's own unlocked ones. Evilities learned by a specific Class can be still passed on to others through Reincarnation(for Generics only) or the Class/Chara World.
In Disgaea 3 and Disgaea 4
In Disgaea 3: Absence of Justice and Disgaea 4: A Promise Unforgotten, each character has 2 Evility slots; the first one is taken by the character's Unique Evility while the second one is available for freely equipping any learned Common Evility. In Disgaea 3: Absence of Detention and Disgaea 4, Monsters have an additional slot for Common Evilities.
In Disgaea 5
Characters still have a fixed Unique Evility(each main character will gain a second one throughout the story), but the way Common Evilities that can be equipped has changed.
Characters have a number of Evility Slots and each Evility has a Slot Cost, with characters being able to equip as many Common Evilities as they can afford within their Slot limit. Units start with 5 Slots, but they can be increased by the following methods:
- A slot is gained when a character first reaches levels 50, 100, 300, 1000, 2000, 5000 and 9999.
- A slot can be chosen as a reward for completing the Chara World, up to 5 times.
- A slot is gained by defeating Miss Evil in the Chara World in Super Overlord difficulty, up to 3 times.
Thus, characters can reach a total of 20 Evility Slots. New slots are gained permanently, so they are kept through Reincarnations.
During the post-game, it's also possible for characters to gain special Slots for equipping aditional Unique Evilities:
- After completing the story, a bill can be passed at the Assembly to make a character gain a new Unique Slot
- A slot is gained when a character lands a killing blow to Carnage Dark in the "Evil God of Tyranny" stage
- A slot is gained when a character lands a killing blow to the Prinny Overlord in the "Overture of Downfall" stage
The Unique Evilities of Generic classes can be learned through the Sub-Class system, by choosing one as a sub-class and maxing out its rank. Unlike Common Evilities, all Unique ones use only one slot.
