Deep Magic Volume 1
Gird the Spirit
1-level Abjuration
Casting Time: 1 reaction, which you take when you or a creature within 30 ft. of you is hit by an attack from an undead creature
Range/Area: 30ft.
Components: Verbal, Somatic
Duration: 1 minute
Damage/Effect: Protection
Your magic protects the target creature from the life-sapping energies of the undead. For the duration, the target has immunity to effects from undead creatures that reduce its ability scores, such as a shadow’s Strength Drain, or its hit point maximum, such as a specter’s Life Drain.
This spell doesn’t prevent damage from those attacks; it prevents only the reduction in ability score or hit point maximum.
Available for: Cleric, Druid, Paladin
