Shadow Embrace is a stacking warlock Affliction talent that both increases the damage done by the warlock's Shadowdamage-over-time spells to the target and reduces the effect of healing-over-time spells.
This talent plays an important part in the spell rotation of high-level Affliction warlocks. By beginning the attack with a Shadow Bolt and a Haunt the warlock can apply two layers of Shadow Embrace on the target, increasing the damage of subsequent Shadow DoT spells until the effect wears off.
Patch 3.3.2 (2010-01-02): This effect can now stack up to 3 times, up from 2. However, the periodic healing reduction effect has been reduced from 3/6/9/12/15% to 2/4/6/8/10% per application.
Patch 3.1.0 (2009-04-14): Now only increases the damage done by your shadow damage periodic spells.
