poison

[Silverthorn]

dunno why it hurts other opponents, though...
I'd use an itr in the bottle similar to this one:

Code:

itr:
kind: 0  x: -30  y: 20  w: 1  h: 1  dvx: 0  arest: 7  injury: 5  effect: 5
itr_end:

While the frame containing that itr runs on state: 18. Not sure if that works but I think it's worth a try
