Necro Stalker

Necro Stalkers are level 61 elite venom spiders found in Naxxramas.

Abilities

 * Poison Charge: Does 2500 damage and adds a debuff to nearby players that ticks for 2500 nature damage every 3 sec. Can be cured.
 * About 80k hit points.

Strategies
The raid should be spread out to minimize the amount of players who are hit with Poison Charge. Focus fire and kill them immediately.

If you stack up they will still poison charge and wipe you that much faster.
