Shockwave Hammer

Here is the example of the skill in the Unit Creator

The Shockwave Hammer is an ability used by the Righteous Paladin, it consists in that the unit will raise its weapon or arm (if it lacks a weapon), the hammer will appear in golden color in the sky at a height no higher than a Giant Samurai, then the unit will lower its hand rapidly causing the hammer to do the same by hitting the ground, causing minimal damage to affected units and resetting the cooldown of their weapons and abilities. It has a moderate AoE range, so it is effective against groups, although due to its low damage, it will likely not kill most of them in one hit.
