Game is amazing, all the sounds and art look great and it's easy to lose track of time playing it. Really fresh idea with the inventory management, thought some items were a bit useless and it could have been clearer visually how your armour affects the other tiles, the green flashes go by too quick to understand, maybe a battle history too, I died to the King int 2 turns and had no idea why or what effect caused it, had lots of fun playing it, starting a second run now
Hover over him to see his abilities. He gains regen each turn, and gains thorns and rage when you hit him. The regen isn't a big deal, but the thorns can wreck multihit strategies like shiv or cleaver. Ironically, thorn+turtle works pretty well against him; with enough defense and at least 2 thorns per turn he'll eventually die if you just don't attack him.
