Strength of the Underworld
Level 3 · Necromancy · Ritual · Concentration
You call on the power of the dark gods of the afterlife to strengthen the target's undead energy. The spell's target has advantage on saving throws against Turn Undead while the spell lasts. If this spell is cast on a corpse that died from darakhul fever, the corpse gains a +5 bonus on its roll to determine whether it rises as a darakhul.
