my idea for this trap is a mechanical skeleton trap an upgraded version of the skeleton trap but better and a separate trap.
stats:
lv.1 th9 spawns 3 mecha skeletons all having the health of a lv.3 barbarian and does the same damage
lv.2 th9 spawns 3 mecha skeletons all having the health of a lv.5 barbarian
lv.3 th10 spawns 6 mecha skeletons all having the health of a giant
tile radius:5
you get 1 at th9 and 2 more at th10
plz comment and look at summoning spell my other post
