Undead Thrall

Infected: (status condition) When a creature becomes infected, they gain 1d4 poison stacks. Whenever an infected creature takes damage from poison, they make a [V] roll (10 or higher to succeed). If they succeed the roll, they lose 1 poison stack. If they succeed the roll by 4 or more, this condition ends. If an infected creature dies, it becomes cursed, and then rises from the dead as an Undead Thrall with full health after 1d8 hours.

Poison: (stacking debuff) At the beginning of each round, creature with a poison stack takes 1 damage for each poison stack they have.

Cursed: (debuff) The creature effected cannot regain hit points from spells. This effect counts as a disease and can be removed by spells, items, and abilities that remove diseases.
