If you want to play with slimes, get a P/P Jade Oozeling
, now that one packs a wallop.
I use him sometimes, and wish I could put him onto more teams. Basically, just about anything he gets both DoTs rolling on and maybe an Absorb that isn't aquatic or have SS/SS or some big heal is headed for death, but he normally gets 3 casts off at best, and is only really effective when both DoTs are stacked. If he had a better racial he would be a real executioner though. On the plus side, he is not very common in PvP, and I bet a lot of Crow users FREAK when both DoTs tick and their racial is gone in 2 turns, lol.
