Chromatic Shield

Thin wisps of rainbow light surround one willing creature you can see within 30 feet of you, which may be yourself.

When the target next takes fire, cold, poison, acid, thunder or lightning damage they gain resistance to that damage type for the remaining duration of the spell, including against the triggering attack.

At higher levels. For each level above fifth you cast this spell you may target one additional creature within 30 feet.
