Poisonous Skitterer

Poisonous Skitterers are venom spiders found in the Arachnid Quarter of Naxxramas. Roaming the halls, they attack in packs. They cannot be tamed by a hunter.

Shield wall and Challenging Shout are old-favorites. Use Area Effect damage to take these down fast. Healers should be sure to keep your cloth-wearers alive.

This is when that Necro-Knight's Garb really shines.

Another Take: We had little success with AOE taunt/Shield Wall, it usually ended up with our entire raid dead. Here's a better plan: Pally runs in with shield and aggroes all the spiders. send 2/3's of your warriors in to grab a few spiders each, with the other 1/3 standing among the clothies to pick up any that aggro healing. Assist a few spiders down, then ranged aoe the rest. No one dies, mana stays up, the pack goes down quick. (The pally pull isn't entirely neccessary.)
