Patch changes

Patch 5.0.4 (2012-08-28): Redesigned.
Hotfix (2011-02-18): Instant-cast Shadowbolts from Shadow Trance (both the talent and [Glyph of Corruption] versions) should no longer consume charges of [Backdraft] if both procs are available. Shadow Trance will always take priority and be consumed first when Backdraft is active. Subsequent Shadowbolts will consume Backdraft stacks.
Hotfix (2011-01-18): While Nightfall is active, Doomguards will not instantly cast [Doom Bolt].
Patch 4.0.1 (2010-10-12): Now a Tier 5 talent (was Tier 4).
Patch 2.2.0 (2007-09-25): This ability can now trigger while the Warlock is sitting.
Patch 2.0.3 (2007-01-09): When a Warlock is under the effects of [Backlash] and Nightfall, only one of the effects will be consumed by a Shadow Bolt cast.
Patch 1.3.0 (2005-03-07): Fixed a bug where the Shadow Trance effect was lost without benefit. Previously, the talent had a 3%/4% chance of triggering. It now has a 2%/4% chance of triggering, and the tooltips have been updated to accurately reflect this change. The Shadow Trance buff granted by the Nightfall talent will no longer be used up by a Shadow Bolt that was in mid-cast.
Patch 1.1.0 (2004-11-07): Added.
