Bound in Death ◆ (healing, void) The tomb jelly splatters some of its substance on a willing undead creature within its reach. The target regains 5 void healing HP and its melee Strikes get the benefits of tomb curse until the end of its next turn.

Flesh-dissolving Acid A tomb jelly's acid damages only flesh.

Tomb Curse (curse, divine, void) A creature hit by a tomb jelly's pseudopod takes 1d6 persistent void damage. If the creature dies while it has this persistent damage, its corpse is affected by Peaceful Rest, except the tomb jelly can still dissolve its flesh.
