"Makes the hero attack the nearest defensive building with his fists, causing it and buildings behind it to be shocked."
Shock Knuckles is an ability that can be used by Pvt. Bullit.
When used, Pvt. Bullit approaches the nearest building and hits it with his fists, stunning the building as well as launching several balls of electricity, which shock any buildings they touch, in addition to dealing a small amount of damage to all affected buildings.
These balls of electricity are also capable of triggering Mines as well as damaging and stunning friendly troops.
Each use costs 6 more Energy than the previous one, with a starting cost of 3 Energy.
The Shock Knuckles can affect an area larger than that of a Shock Bomb, while being cheaper initially. When sufficiently leveled, the Shock Knuckles' shock duration is only marginally shorter than that of a Shock Bomb, so it makes a good substitute to a Shock Bomb if the Shock Knuckles' cost is lower.
Due to the linear nature of his ability, it is important that you ensure Pvt. Bullit faces a direction where many defensive buildings are behind him whenever you use his ability. The Shock Knuckles will not be effective if it hits only a single defense and subsequently spreads behind to damage non-defensive buildings.
