Belial, the First resets the buff (unintended) of Curse of Belial but doesn't reset the debuff (intended) when played on an opponent affected by Curse of Belial with 1 turn left. This results in the buff gaining 25 height per turn continuing after the debuff has been removed, giving you that effect for another 3 turns.
