Aspect of the Viper

This aspect is very helpful for reducing your downtime when farming or grinding, and switching to it during longer PvE fights (raids) can keep you going much longer.

Kill Command

This is an excellent ability. It helps your pet keep aggro after you land a crit, which is exactly the time you might pull it away from it. In addition, its cheap damage. Note that both ranged and melee crits will trigger Kill Command. It deals your pets normal damage plus the bonus.

Steady Shot

This might not look too good on paper, but is a worthwhile skill. It can be used between attacks for extra damage without interfering with your auto shot damage. When multishot may be too costly to use it can also save you a lot of mana.

Snake Trap

Fun trap, the snakes hit for about 20 damage and can apply several poisons to the target; Deadly Poison (75 dmg every 2 seconds for 15 seconds) Mind Numbing Poison (Cast time increased by 50% for 12 seconds) and Crippling Poison (-50% movement speed for 12 seconds). They don’t apply all those poisons instantly though, it takes some time. Their melee damage really screws anyone trying to cast something non-instant. An instant AE will kill them easily though. Note that they will attack anything hostile nearby when the target they were on dies. Risky in instances.

Misdirection

Misdirection is awesome for PvE. It isn’t just a great way to dump some of your aggro onto the MT, it’s also a great pulling tool. Put misdirection on the tank, land some big shots on the mob you’re pulling and it will run straight to the tank.
