So the updated Lord of Bones the great avatar of mykrul had 326 hp what was 100hp less then grym. And he was lvl 11 we killed it in 2 turns just two of us. And it had just 19 armor class. For a God's avatar I whould recommend like 30 armor class and least 500 hp.
He could not do anything. Pls if some dev is reading this make another difficulty lvl or revisit tactican. Cuz the 50% more hp is not applyed to every enemy in tactican mod. I don't know if it's a bug or intentionally but it's to easy.
