Periodic

 is a type of ability that exists in different variations for the different Damage Schools. Periodic abilities are active abilities, which means they will only activate if the Creature has a full Bloodlust Counter.

Variations
abilities can appear as certain activation, or with a chance to activate. They will activate during the card's turn. They always targets one enemy, and the damage ranges between 1 and 2.

Explanation
Periodic damage stays on the creature until it is removed with a Dispel ability, or until the creatures leaves play.
