Hey! I have idea! What about a vampire that heal 1 HP for every enemy it attack. It could be either three or fourth bones as level and the stats would be 1 attack and 4 HP at merge one. At merge 2 could have 2 Attack 5-7 HP and heal 2 HP for every hit. Mabye to OP but It's still an idea
(Would draw a design but I'm to tired to do it.)
