Undead Fortitude

Free Ability

1,000 gp

If damage reduces the zombie to 0 hit points, it must make a Fortitude with a DC of 5 + the damage taken, unless the damage is radiant or from a critical hit. On a success, the zombie drops to 1 hit point instead.

You watch the zombie, battered and broken, momentarily falter, then stubbornly cling to existence, its decayed form unnaturally bolstered by a grim, unyielding resilience, refusing to fall despite its grievous wounds.
