Wizard quad advice.

[Kaezyr D`Shiv]

Quadding gnolls at 30 is definitely going to be rough, I think these are more for 32+ and after the 34 AoE much more efficient. Honestly even though you have the first snare spell, that doesnt mean you have to use it.

Make use of SoW buffs from others when you can, and strafe while running for that little extra. Circle of Force at 34 makes things better, and levels is the best thing you can do about resists. Always quad the lowest blues of your level if you can handle it. At 30 if I am not mistaken, level 22-29 mobs are blue range.

I think I quadded maybe Brutes out in Warsilisks woods around near the Dalnir caves, perhaps after that giant skeletons in RM near Lake Rathe zone if I recall.
