Crystal spiders chase their enemy down and fight until death. Changes target frequently.
They are similar to Giant Spiders, but have less attack power and more defense. You should be careful with them since they're found most of the time in groups and in small places, also they paralyze you very often, making it hard to keep distance. Since Summer Update 2010, crystal spiders drop Jewelled Backpacks.
Watch your step! They are located in smaller areas along with Wyverns, Ice Golems and other Crystal Spiders, so you may have trouble outrunning them. Strike hard and fast with a Knight blocking and have Paladins or Mages attacking with offensive spells to dispatch it quickly. Soloing them on a Knight can be risky. Mages should use exori vis and while druids should use a death rod, sorcerers should use an energy wand. Keep in mind they are similar to Giant Spiders but use weaker melee attacks and paralyze, so running them is not needed. Paladins should keep distance and use Ethereal Spear to kill them quicker therefore lowering the risk of running into other spawns.
