I propose the following buffs to the Chromalisks:
-An HP boost
-Themed Chromas should get the tongue attack that does piercing. Their hawk-a-loogie should do elemental. Salamanders, however, I think it would behoove the salamanders to breathe fire instead.
-Normal Chromas should get a hawk-a-loogie attack that also might do elemental and inflict stun.
On T3, Chromas have a fair amount of hps, considerin' they usually come in pretty large groups, I'd say.
