I did this today and had trouble with it too, all I did was spam the water attack on the dog first and hoped for a crit, killed dog then the chameleon also make sure you take Light/Wind/Nin/Tai damage so you can kill the puppets after, or some poison damage.
Ending up killing chameleon by a hair, casted the other melee mystery straight after my water move and it went first in the round killing the chamelon.
I didn't take any at first and had to re-do the first part with the summons. This post was last edited by Xianora at 2017-2-6 05:29
