DESCRIPTION
Suited Susceptivity fundamentally alters the morphology of a creature to afflict it with a weakness of the caster's choice. If an element (fire, cold, acid, electricity, or sonic) is chosen, the creature gains vulnerability to it (50% extra damage). Anything else chosen must be a spell subtype with a descriptor -- for example, light, fear, poison, disease, sleep, etc. -- for the target creature to gain a vulnerability to that effect (-4 penalty to all saves against that effect).
