Wowwiki quote
" The snakes have 3 rogue-style poisons:
Crippling Poison: Enemy movement speed is reduced by 50%.
Mind-Numbing Poison: Enemy spell-casting speed is decreased by 50%.
Deadly Poison: Enemy gets 15 nature damage over 12 seconds. Stacks up to 5 times.
[...]
Snakes at level 80 have 107 hp and 9729 armor.
The Vipers hit for 38-53. 4 of these appear.
The Venomous Snakes hit for 16-24. 4 of these appear.
Both types of snakes use all 3 of the different poisons (Crippling, Mind-Numbing, and Deadly)."

Also, I've read somewhere (wowinsider?) that SV dmg is also boosted by pet's 8% spell dmg boost (Wind Serpent?). Is it true, because I couldn't find any information about this. In this case considering let's say our personal dps will be better with 8% spell or physical dmg debuff?
