This is a passive ability similar to Backlash.
All levels of Corruption have the same chance to proc. Since recent changes nerf your use of lower level spells (using +dps instead of damage from the spell) you can use this to tremendous effect in instances and raids. Allow the tank to build aggro then apply level 1 Corruption to each target except the main. This will generate negligible threat but counts toward procing nightfall. It also has the added effect of causing the Shadow Embrace.
One of the main reasons why warlocks put points into the Affliction talent tree, Nightfall can dramatically increase the warlock's damage output, assuming it actually activates.
Nightfall does not proc when Corruption or Drain Life is cast. Instead, Nightfall has a 4% chance to proc EVERY time a Corruption or Drain Life spell ticks damage on an enemy target. Corruption ticks every 3 seconds, but can be placed on multiple targets to greatly increase your chances of proccing Nightfall. Drain Life ticks every 1 second. A common tactic against a single target is to place Corruption on the target, and then repeatedly Drain Life until Nightfall procs.
A given casting of Corruption (with 6 ticks) has a 21.7% chance of proccing Nightfall on one or more ticks. A given casting of Drain Life has an 18.5% chance of proccing Nightfall on one or more ticks.
Multiple procs of Nightfall do not stack. The warlock can only have one Shadow Trance buff at a time. It can, however, proc multiple times from the same Corruption/Drain Life spell.
Glyph of Corruption stacks with this, giving an increased chance for the same Shadow Trance effect on Corruption ticks.
- Patch 1.3.0 (07-Mar-2005):
- 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 shadowbolt that was in mid-cast.
