Warden Ability: Shockwave

As of the moment the warden can be easily cheesed by simply pillaring up with blocks. A potential solution to this issue could be to give the warden its own unique ability. If the warden is constantly being attacked without successfully landing a single shot on you it should be able to use a special ability: the shockwave. The way this ability would work is when you are in a position where the warden cannot get to you it will create a shockwave in the direction it is facing and damage you using a sort of earthquake. This would also have some useful functionality to it. When the warden performs the shockwave it will crack nearby blocks such as deepslate allowing you to easily get these cracked building block variants naturally.
