The Riftstalker Bloodfiend is the Slayer Boss in the Vampire Slayer branch. It is unique to the Rift Dimension at the, and does not require any previous Slayer completion to access.

Behavior
When the Riftstalker Bloodfiend is spawned, all nearby Vampires except the Bloodfiend himself and the Clotgoyles spawned by him are passive against the player who spawn the boss.

The Riftstalker Bloodfiend constantly drains every second. Every few seconds, or if the player is too far away, it will enter its Spectral Form to move. It will return back to normal once it lands. Once the boss is at half health, it will use its Mania ability, becoming immune for 22 seconds. A circle of red blocks will spawn, along with a green ring inside of it. The player must stand in the green ring to not get their taken. Being outside of the 13 blocks circle incurs every second. The boss spawns Clotgoyles that reduce the player's maximum by 1 after their Mania ability. After the Clotgoyles are killed, the hearts are retuned to the player. They will respawn unless hit by the Riftstalker Bloodfiend 's Stonewrath. As a vampire, when at or below, it takes when attacked by a player with a Steak Stake.

Instead of draining every second and taking away  per failed Mania, the boss now drains  every second and takes away  per failed Mania. Now, the Mania phase starts upon the boss reaches 60% health. Every 7 seconds, a pair of Twinclaws are spawned, with one in front of the boss and one behind the boss. The frontal claw is shot towards one of the players fighting the boss, and takes away on hitting any players fighting the boss. As a vampire, when at or below, it takes when attacked by a player with a Steak Stake.

Instead of taking away per Twinclaws attack and  per failed Mania, the boss now takes away  per Twinclaws attack and  per failed Mania. The boss has 2 Mania attacks now, starting at and. During Mania attacks, the boss uses its Impel ability, during which players have to complete the boss's order (one of the following: CLICK UP, CLICK DOWN, JUMP, SNEAK) within 2s, or else are taken away. After the first Mania attack, the boss starts the Stonewrath ability. After the second Mania attack, the boss launches a spring made of candles to a nearby location. It can be compacted by clicking on it while alternating left and right click. The spring must be fully compacted within 15s or everything explodes and all players fighting it die. As a vampire, when at or below, it takes when attacked by a player with a Steak Stake.

Instead of taking away per Twinclaws attack,  per failed Mania and  when out of the Mania circle, the boss now takes away  hearts for each of these attacks. The Twinclaws attack can now be used during the Mania attacks. As a vampire, when at or below, it takes when attacked by a player with a Steak Stake.

Instead of taking away per Twinclaws attack,  per failed Mania,  per failed Impel and draining  per second, the boss now takes away  per Twinclaws attack,  per failed Mania,  per failed Impel and drains  per second. The boss has a new Blood Ichor attack, which frequently spawns an ichor nearby which must be destroyed within 25s. When Twinclaws are thrown towards the Blood Ichor, it breaks. As a vampire, when at or below, it takes when attacked by a player with a Steak Stake.
