Here's another monster fit for an april fools game, or just to throw a curve ball at your players, it's the:
Electricity Subtype: Electricity Immunity, the creature recives a -10 penalty to saves against acid.
now comes the 2nd question... remember a little creature called a shocker lizard? I like to call them pickachuu(not sure as to how to spell cause I don't deal w/ pokemon cards) but they have this ability... it start low w/ it's electrical discharge then for each one around it it feeds off them... the effects can be... shall we say... shocking?
I think it came up to like for 11 shockers the dmg was 22d8... 2d8 for each one... *l* now that would be a site...
