Shade

Freyar's writeup looks good, except I'd clarify that it is fire damage. In fact, I'm not sure if we need the "Unless magically protected by fire" text. Instead, perhaps it should read:
"Any foe so showered takes 1 point of fire damage per round. A victim damaged by the shower also suffers a -4 penalty on attack rolls, skill checks, and ability checks, as well as a -2 penalty to Dexterity, for 2d10 rounds."
I agree with Cleon that Cha-based seems the most appropriate in this case.
