Patch 7.1.5 (2017-01-10): Damage reduced by 25%.
Patch 7.0.3 (2016-07-19): Redesigned as a level 90 talent (was 75). Now sacrifices the demon to sometimes deal additional Shadow damage to the target and other enemies within 8 yards for 1 hour.
Old: Sacrifice your demon to gain one of its abilities, and to increase the damage done by your [Drain Soul], [Haunt], [Drain Life], [Chaos Bolt], and [Shadowburn] by 25%. Does not apply to spells affected by [Fire and Brimstone]. Also causes you to regenerate 2% of maximum health every 8 sec. Lasts 60 min or until you summon a demon.
Hotfix (2015-06-23): Grimoire of Sacrifice should no longer be incorrectly canceled at the end of a raid encounter.
Patch 6.1.0 (2015-02-24): Now increases damage of affected spells by 25% (up from 20%).
Patch 6.0.2 (2014-10-14): No longer available to Demonology warlocks. A new talent, [Grimoire of Synergy] is available in its place.
Hotfix (2013-10-03): Grimoire of Sacrifice should no longer incorrectly reduce spell damage while Fire and Brimstone is also active.
Patch 5.4.0 (2013-09-10): No longer affects Drain Life. For Affliction Warlocks, Grimoire of Sacrifice now increases the power of various single target spells by 20% (down from 30%).
Patch 5.2.0 (2013-03-05): Now increases the damage of abilities by 15% (was 25%) for Destruction Warlocks and 25% (was 50%) for Affliction Warlocks. In addition, it now provides the spell [Whiplash] instead of [Seduction] when a Succubus is sacrificed.
Patch 5.1.0 (2012-11-27): The additional damage Grimoire of Sacrifice grants to Chaos Bolt is now dealt over 3 seconds. This damage over time behaves in a manner similar to a Mage's Ignite, where each new damage over time effect rolls into the previous one. This means that no damage is lost if a new damage over time component is re-applied before an existing one fades.
Patch 5.0.4 (2012-08-28): Added.
