Lava Fish

Debatably the easiest of the bosses, as its gimmick is just stacking burns. The boss itself doesn't use any of its skills, with the exception of aegis, when its on low health, it just moves and attacks you with its default attack. However, it should be noted, that bosses are much stronger, than regular enemies and can easily 2 tap your units. The general strategy for lava fish is having a tank, a healer and some units that can attack from a distance. The rest is just simply keeping your tank alive and move out of newly formed lava tiles. It should be noted if you do take too long your healer might not keep up with the burns stacks, unless you have cleanse or any other burn removal. Water creation skills also trivializes the burn damage. Upon defeat lava fish drops lava heart, lava scale armor and lava scales, that can be used to craft more armor. Also it should be noted, that any boss fusion or offspring loose the giant trait, so if you wish to obtain a boss in all its glory you need to capture them.
