The Blood Punch is a new type of melee attack introduced in Doom Eternal. Unlike the standard melee attack, the Blood Punch has a limited number of uses and must be recharged by performing Glory Kills on enemies. It acts as a highly powered-up melee punch performed by using left fist of Slayer.
When used, the Blood Punch causes a large explosion which can damage a number of enemies in the immediate vicinity around the player. The secondary shockwave set out by Blood Punch can easily destroy a number of Fodder demons. The Blood Punch is particularly useful against the Cyber-Mancubus as it will immediately destroy the demon's armour. Blood Punch is also useful in destroying destroy Carcass' energy shield and Archvile's flame wall in one hit and it is also powerful enough to one-shot Pinky. All enemies killed by the punch (not the shockwave) will drop health.
Its effectiveness can be upgraded even further through the use of the Punch and Reave rune, which makes enemies killed by the Blood Punch shockwave drop health.
