Defence idea.

Unware if this has been suggested, I apologise if it has.

Heres my idea..

Dark Elixr Defence.

A silver/grey tower similar to wizard tower but shape of an archer tower.. Each level the tower gets darker, and maximum level makes it black diamond effect.
On the top, could be a Valk.. With each level her hair changes colour.

Her weapon - Shooting tomahawks.


Bombs/Traps ideas..
a new trap, that comes up from the ground and opens up a black hole and sucks the troops within two tiles into it.

another new trap, looks like a bear trap and clamps a group of troops that's been dropped.
