It currently just deals damage as long as it is being hit with the element; it should:

1. if it has an elemental heart, hurt them 1 second, dealing no damage, but breaking the heart.
2. if it has no elemental heart, hurt them 2 seconds, dealing 5 damage, and, if still being hurt at the end, have 1 second of wait time; no damage dealt during the wait time, but if no longer hit by element stop hurting.
