Every hero will be randomly assigned a hero ability when they are created. Current hero abilities are: Enrage, Poison and Regen. Enrage: Damage increases by 1% for each 1% of HP lost. Poison: Deals 10% damage to infected heroes before they act. Regen: Heals 10% before the hero acts. If you do not like the ability assigned to your hero, you can re-roll this ability using the "Reroll Ability" function on the hero screen. This function requires a small fee in KKT.
