In Blizzard's World of Warcraft Cataclysm expansion Chitter is a rare spawn who can be found in the Redridge Mountain zone located in the Render's Valley area he is the only (fast moving) spider in the area so if he is there he will not be hard to spot. He tends to be found rapidly circling round a tree. Not to be mistaken with Chatter another rare spawn spider found in the Redridge Mountain zone. Note this area may phase as you do the Redridge Mountain quests but Chitter will still be there.
Chitter is a level 18 rare mob with around 600 hit points he attacks with a basic melee attack and also uses two special abilities poison which causes damage over time and paralyzing poison which stuns the player hit for a few seconds. Chitter is quite easy to dispatch just be careful of the elites that be may around.
