fistful of dollar (ultrakill)
At the split-shot sparkle, an airborne Coin can be Parried using the Feedbacker to turn it into a hitscan projectile. It will also automatically target the closest enemy, dealing damage and giving the [+FISTFUL OF DOLLAR] Style Bonus. Once the coin projectile hits an enemy or surface, it will turn back into a normal coin and bounce directly upward into the air from the point of impact, resetting its airtime and allowing it to be shot or punched once more.
While a punched coin by itself only deals two damage, each punch increases the coin's damage by one, similar to a coin chain, though this caps at 5 damage if the coin were to only hit a surface, only allowing for the first three punches to add damage. However, this cap does not apply to coins bounced off of enemies, and by constantly hitting the coin after it bounces off an enemy, the damage multiplier can be increased to the point of even being able to instantly kill bosses.
A coin punch does the same damage as a Standard Revolver ricoshot and gets the same damage multiplier from head/limbshots.
