Black Pudding

When a pudding that is Medium or larger is subjected to lightning or slashing damage, it splits into two new puddings if it has at least 10 hit points. Each new pudding has hit points equal to half the original pudding’s, rounded down. New puddings are one size smaller than the original pudding.

Trigger: While the pudding is Large or Medium and has 10+ Hit Points, it becomes Bloodied or is subjected to Lightning or Slashing damage. Response: The pudding splits into two new Black Puddings. Each new pudding is one size smaller than the original pudding and acts on its Initiative. The original pudding’s Hit Points are divided evenly between the new puddings (round down).

The pudding can move through a space as narrow as 1 inch wide without squeezing.
