Cluck Off! transforms all visible enemy minions into helpless chickens for a short duration, causing them to halt all aggressive actions. Once in this state, tapping on them will deal heavy damage. More powerful minions may require multiple finger-taps in order to be squashed. Since the effects of this spell are temporary, the faster one taps on valid targets, the better! Once the spell duration has expired, any and all surviving chickens revert back to their original form and behavior.
Cluck Off! becomes available for research and unlocking once a Dark Library has been built. Keepers should note that there is a fairly significant mana cost to use this spell. Every time Cluck Off! is cast, it gains spell experience. This eventually will increase the spell's level, which in turn will increase the spell's effectiveness.
Strategic use of Cluck Off! -
During defense: this spell can lock down powerful foes to stop them from attacking your buildings/traps/minions, while you assist in bringing them down by tapping on them
During attack: this spell helps to deal with some of the more devastating foes if your army is otherwise ill-equipped to deal with them (for example: a defending Ghost, if your army has no ranged or flying units)
Have fun with this one, Keepers! There aren't many better ways to tell your enemies to Cluck Off! That is, of course, unless you're... chicken.
