Patch changes

• Patch 9.0.1 (2020-10-13): Re-added. Now affects application chance for all poisons, and now also causes poisons to apply to weapons 33% faster. Additional rank added.
  
• Patch 7.0.3 (2016-07-19): Removed.
  

As Assassination is the only specialization using poisons, it's highly unlikely this is still in the game, regardless what database sites say.

• Patch 5.0.4 (2012-08-28): Improves Wound Poison instead of Instant Poison.
  
• Patch 4.0.1 (2010-10-12): Changed from an Assassination talent to an Assassination specialization.
  
• Patch 3.3.0 (2009-12-08): Bonus chance to trigger Deadly Poison from this talent increased.
  
• Patch 1.12.0 (2006-08-22): Added. Replaced [Improved Instant Poison] and Improved Deadly Poison.
