Notes
This talent makes "drain-tanking" semi-possible: the warlock tactic of casting Drain Life while being attacked. Combine this talent with Soul Siphon and Improved Life Tap for best results.
A 70% chance to avoid interruption is okay, but it's still rare that you get all 5 ticks of Drain Life when something is beating on you. It works out to a 34.3% chance that you'll make it through 3 attacks without being interrupted. Many Warlocks are upset that the Mage version of this for Arcane Missiles is a 100% chance to avoid interruption. On the other hand, if Drain Life could never be interrupted, it would be practically impossible for a regular monster to kill a Warlock. Regardless of their complaints, most Affliction Warlocks take this talent.
