Hmm, if you put the hp to 0 it will just ignore that condition. You could try setting it to hp < 1 that should do the trick. And since raise gives the player a buff be sure to add that NOT has buff id for raise so it wont try to spam it.
167 Swiftcast
148 Raise
So you would set hp < 1, HAS NOT buff 148, and has buff 167. This would only cast on somrthing with hp < 1, that doesnt already have the raise buff, and only if you have swiftcast on.
