How Does WoW Forever Let Warlocks Keep a Sacrifice Bonus and a Demon?
Demonic Pact lets Demonology Warlocks retain a sacrifice bonus while summoning a replacement companion. Here is what Blizzard confirms, and what still needs checking.
WoW Forever's Demonology Warlocks can keep a Demonic Sacrifice bonus while fighting with an active demon. Blizzard's latest class overview describes Demonic Pact as sacrificing one companion and immediately summoning another, without losing the sacrifice benefit.
That removes an old trade-off. You can choose a demon for the bonus it leaves behind and a different companion for the fight ahead. It is a confirmed part of Blizzard's class design, not an announcement that Demonology has just received a new damage buff.
Sacrifice one demon, fight beside another
Under the old arrangement, Demonic Sacrifice killed your active companion and granted a bonus based on the demon sacrificed. Summoning another demon removed that effect. Keeping the bonus meant going without the pet.
Forever reworks that relationship through Master Summoner, Demonic Sacrifice and the Demonic Pact capstone. Blizzard says the replacement companion can fight beside you and work with Soul Link while the sacrifice bonus remains active.
The two choices now have different jobs. The sacrificed demon supplies a benefit; the replacement supplies the active companion. Blizzard describes combinations supporting Fire damage, Shadow damage, mana regeneration or survivability. The useful question is what your spells need and what you want your pet to contribute, not simply which demon has the largest damage number.
The overview does not provide a complete demon-by-demon bonus table. It also does not establish that multiple sacrifice bonuses can be stacked. Plan around the confirmed sacrifice-and-replacement interaction, not combinations the video never describes.

Three Warlock paths, not one damage ranking
Demonology also gains a finishing tool through Decimation. Blizzard says Shadow Bolt or Searing Pain hitting an enemy below a health threshold activates the effect, removing Soul Fire's Soul Shard cost and substantially reducing its cast time. The narration does not give that threshold or the exact reduction.
Affliction takes a different approach. Damage-over-time effects build pressure before the Warlock commits to a drain. Wrack, described as a 31-point talent, channels damage and increases the damage the target takes from that Warlock's other Shadow spells. It is not described as a bonus for every Shadow caster in the group.
Destruction puts Incinerate at the bottom of its talent tree. The spell deals additional damage when its target is already affected by Immolate, giving those two spells a direct interaction. Blizzard presents the redesigned tree as supporting Fire and Shadow together.
Those descriptions explain how the specs differ. They do not establish which one wins a damage comparison, handles every dungeon best or needs the least downtime.
What the spotlight does not establish
The current beta's level-30 cap should not be confused with access to every talent featured in a broader class overview. Check the current talent requirements before planning a beta build around a capstone. This is not a level-1-to-30 talent route.
Exact sacrifice values, pet combinations, execute thresholds and relative damage still need current build verification. The practical change is narrower and useful enough on its own: Demonology no longer makes the sacrifice bonus and an active companion mutually exclusive. Start with the benefit you want, then choose the companion you want beside you.
