Giant can 1-shot anything
I just found out that giant can 1-shot anyone when the target is pushed up against the corner wall (3 or less surrounding tiles) and there's no tile in the back for the target to land on.
Final round i was left against 3 star full hp monk at the left side of the arena at the tile that can be attacked from 3 other tiles, i had left alive very low hp knight, full hp princess and full hp giant. Knight was fighting monk the entire round and at the very end my giant came up to full hp 3 star monk, used his ability and monk just disappeared when he landed. Giant came up from right side of monk so when giant used his ability there was no other tile higher or lower for monk to go and i think the game just got confused?
I will try to catch this on video later
