If anything, this monster looks too strong. It’s going to reliably get kills every turn (100-130TU) and has petrify revenge which we know from Skeleviathan is kind of nuts. Camouflage also makes it annoyingly awkward to deal with. It’s another power crept mythic that pushes out legendaries.
Ironically, I think it’s actually got too many attacking moves that you simply don’t need them and it would be stronger with some changed. I mean, it literally sets up raw stealthbreak on entry and if they’ve lost stealth you go for double sneak attack. Only a single kill and double bloodcrave is charged… so why does it even need to be Medusa and do the petrifying gaze stuff?? Seems like very lazy design to me, whereas Nagandia is far more interesting and coherent.
So I find this monster a bit annoying to look at. Easy, reliable kills and mostly piercing kills is boring power creep while the moveset won’t be utilised fully as you play it because it’s simply “click and kill” and then petrify revenge is the thing that pushes it above many of the previously released strong mythic sweepers so we’re pressured into playing this boring design next to the other much more interesting designs.
Maybe I’m an old man shouting at the clouds but I loved the days when we were playing things with killer moves or needed some proper set up to charge their blood move.
