Status Ailment

A Status Ailment is a condition that afflicts characters and causes them to behave abnormally, reducing their abilities in combat.

Various skills throughout the games can inflict ailments, and there's Specialists and Evilities that give your normal attacks a chance to inflict them as well. They usually last 3 turns(unless healed earlier), and resistance to each of them is only gained by equipping the corresponding Specialist or Evility.

The chance of successfully inflicting an ailment doesn't grow with your stats, depending only on the base chance of the attack/skill inflicting it and the target's ailment resistance. In Disgaea 5(and possibly previous games), if the target's RES stat is higher than the inflictor's INT then they get increased resistance to all ailments.

Below is the list of all the Status Ailments in the Disgaea series:
 * Charm: Attack your own allies.
 * Deprave/Weaken: Reduces all stats.
 * Forget: Disables skill use.
 * Paralysis: Disables movement and evasion.
 * Poison: Lose health each turn.
 * Shrink: Disables attack and skill use.
 * Sleep: Unable to move or act.
