Typically I steamroll the lizard teams. It's just a matter of spending a slew of turns rolling my eyes and waiting for the invincibility to wear off so I can kill them. Today after sustaining trivial damage from other sources, Viperia basically 1 shot my entire team. My team is Greater/Superior runed, and include 2 color advantaged heroes.
So, I don't have any of the lizards, and you can't inspect their abilities in game if you don't have them (which is really, really, poor design), so where do all the damage buffs come from, and does this seem legit or shady? Seems like if this was the way she worked, I would see a lot more Viperia and a lot less Shade.
