Butcher

"The Butcher is a reanimated pile of ever-decaying corpses that kills anything in its sight and absorbs the remaining corpses of its enemies. It can also sniff out nearby enemies who were recently injured. It's like an Eldritch abomination, but with a chainsaw and a hook."

The Butcher is a melee oriented class that consumes the health of a target after killing them and can use their corpse as a dangerous explosive tool. It's one of the few classes that does not have a gun.

Decay
Decay is a debuff that lowers the health of the Butcher as time goes on. Unlike the Vampire's Blood Loss though (which removes 3 health points from the Vampire consistently), Decay minuses the user's health by max health divided by 40. This means that the more health you have, the faster it depletes.

Hunter's Scent
Hunter's Scent is an ability that can only be activated when an enemy player is damaged. Once the enemy is damaged, you will see a red mist (known as "scent") around them (which can be seen through walls). The "scent" of the player will only last for 10 seconds and it can be stacked.

Haste
Haste is an ability that can only be activated when the Butcher's health is lower than (or at) 35. This ability increases the speed of the Butcher until it can get some health. After regaining health (or dying), the Blutcher will lose this ability.

Meat Hook
Meat Hook is an ability that allows the Butcher to pull an enemy within a 40 stud radius towards it. This hook also disables the target's backpack once it has been successfully used. You can also use the lock-on feature (by pressing Q over your target) to make sure you can hit your target.

Reload Time: 10 seconds.

Corpse Explosion
Corpse Explosion allows the Butcher to use corpses of both the enemy and ally team to its advantage as long as it's within a 60 stud radius. It's one of the Butcher's most powerful abilities.

Reload Time: 45 seconds.
