Poison per second This page is made to show you the effects of a faster / slower weapon on your ammount of poison procs . You ' ll notice that faster weapons will give you a benefit here . Formulae for % chance to apply poison every second , based on your main / off hand weapon speed / talents / sword spec and equipment . Also see : Attack speed & Haste Application improvement modifiers . Extra attacks . There are several extra attack modifiers in the game , some affect both your main and off hand . All extra attacks granted ( even from offhand swing procs ) are main hand swings , thus greatly increasing the main hand ' s chance to apply a poison . Also , all instant attacks ( Riposte , Sinister Strike , Hemmorage ) swing your main hand weapon . Note : The weapon effects ( Thrash + Sword spec + HoJ , etc ) do not stack , instead they are each calculated seperately . Meaning you have a 5 % chance to get an extra attack from sword spec , and also a 2 % chance to get an extra attack from HoJ , and also a 20 % chance to get an extra attack from Windfury . Overall , the chance of getting at least one extra attack on a swing is 1 - ( 95 % * 98 % * 80 % ) = 25 . 52 % . The good thing about this is that they can also all happen at the same time ( 5 % * 2 % * 20 % = 0 . 02 % chance of this ) , thus resulting in 3 extra attacks . Increased poison application chance . Talents and gear bonuses to improve the success rate of applying a poison all stack together . So , if your base chance is 20 % , you can get + 10 - 15 % from talents , + 5 % from the bloodfang set and + 30 % from the Venomous totem found in Blackwing Lair . Making a total of ( 20 + ( 10 - 15 ) + 5 + 30 ) 65 % for instant poison , and 70 % for deadly poison . If you make a rough estimate that ( at 100 energy ) you can do 5 attacks in the first 2 seconds , then that would amount to 3 - 4 applications of poison . Instant poison rank 6 ( 112 to 148 ) would cause 336 - 592 damage during that time . Formulae . Poison _ Proc % = Base % + Talent _ Improve % + Gear _ Improved % Off Hand Weapon . Off hand poison procs are a linear calculation so this part should be pretty straightforward . Formulae .
