Witch Oaks, as the name implies, are giant oak trees with witches on them. However, unlike what the name implies, it is NOT a tower that spams skeletons at it's base. Witch Oaks are actually similar to poison towers - they launch skeleton minions at enemies, which cling to the unit and smash at it until one of them dies. They will try to attack un-poisoned units.
Infected units will be slowed and continuously damaged for a while, until the skeleton appears to explode like a normal unit. If the unit dies, the skeleton will disappear with it. Damage stacks.
Witch Oaks are 2X2, and costs 10000 dark elixir, available at the same level as the BK. They shoot 1 shot per second.
