New dark troop: Werewolf

The werewolf is a new troop which you can train in your dark barracks. The lower its healthpoints are, the more demage is he making! It costs around 250 dark elixir and lasts around 15 minutes. Its skin is at first colored brown and it's a bit hairy. Then It slowly turns to red, when it is in rage! I do not know, if this unit would be overpowered, i hope it isn't! Leave a comment below if you would support this idea, and let me know how you would find it! Thx, LuKing! Clan: Heldenküche, Level 79!
