We all know Jumping spell's / Archer Queen's power, they can easily
bypass your walls (even if they are maxed!) and destroy anything behind it.
Then you might think like "why the... did I spend tons of gold/elixir into my walls
if they can be ignored with a Jumping spell?"
That's why the fallowing idea came into my head:
Let us "craft" our walls with Dark Elixir!
Only works for walls level 10+ ...
Costs like 100.000 Dark Elixir each wall
and you can only craft 50 / 250 walls, so it's not over powered.
It won't add more HP to the wall, but the Jumping Spell / Archer Queen / Hog
can't jump / shoot over the crafted walls.
