Undeath's Eternal Foe

You invoke the power of a Death domain  as you touch a target for the spell. A crystal blue aura springs up around each of them, fortifying them against the assaults of undeath.

Targets become resistant to poison, necrotic and being knocked unconscious. The subjects also have immunity to the special attacks and abilities of undead that deal ability damage, disease, or paralysis. Targets are cannot be dropped below 1 HP for the duration of the spell or while the caster is concentrating.
