Instant Poison VII
Classes: Rogue
Requires Level 68
Use: Coats a weapon with poison that lasts for 1 hour.
Each strike has a 20% chance of poisoning the enemy which instantly inflicts [161 + 0.10 * AP] Nature damage.
This is currently how Instant poison is looking on PTR. It has 20% chance to do 161 damage + 10% of my AP, say 300 extra in a raid. Roughly every 5th attack will procc an instant untalented (counting combat speccs).
Wound Poison V
Classes: Rogue
Requires Level 64
Use: Coats a weapon with poison that lasts for 1 hour.
Each strike has a 50% chance of poisoning the enemy, causing [112 + 0.04 * AP] Nature damage and reducing all healing effects used on them by 50% for 15 sec.
This is the level 64 rank of wound. It has 50% chance to procc 112 + 4%, say 120 extra in a raid.
Every other attack will procc wound poison.
Counting combat, the only poison talent that we will possible get our hands on is Vile Poison. It affects both, so I won't enter it here.
But straight up, counting every 100 attacks.
20 attacks of 100 will procc instant poison of 460~ damage each = 9200.
50 attacks of 100 will land Wound Poison of 230~ damage each = 11500 damage.
These are very round numbers, but answer us this Mr.Shoehead (that made the last 2 PTR-patches), are wound poison really meant to out-damage instant and deadly poison?
I double checked the math and it's sound. Interesting thing to keep in mind just in case you don't spec mutilate.
