the goblin king
the idea for this hero is he does not take a active part in your army but supplies you with better weaponry and units in return for gold, elixir, and gems
the goblin king takes no part in war or raids and is a npc hero
some ideas so far:
goblin worker (500 gems)- works twice as fast as normal workers but can only be use for a week
troop upgrades that change what they do like:
tomb of the dead (10,000 gold - per witch upgraded)- skeletons have chance to spawn with a bow and arrow
