Purple Eternia Shard
Like every boss, the Spider Queen has a weakness. While all damage sources deal significantly less damage than their original amount (amount of damage reduction varies with each difficulty setting), it is possible to increase damage done by attacking her crystal core when it is exposed. This can be done by killing the spiders she summons.
Defeating the Spider Queen will unlock the Purple Eternia Shard.
The Spider Queen fights at close range, stabbing and webbing her target. She will push-back any defenses that get in her way. She can also summon spiders around her. The queen has very high damage reduction which depends on the difficulty setting. More damage can be dealt to her by killing the spiders she summons. Doing so will cause her to slump to the ground for a few seconds, exposing the purple crystal in front.
At half health, the queen emits a red glow, speeding up attack animations and increasing her attack damage.
Note that she also seems to regenerate health on NM difficulty.
Tips and Notes
- A Barbarian in Turtle Stance can attack the queen up-front whilst taking minimal damage from her attacks and not getting crippled by webs. Stacking a Strength Drain and Healing Aura will greatly improve his survivability.
- Be careful when you turn on Blood Rage, Hero Boost or other toggle ability with a long cooldown (Turtle Stance excluded). These abilities will be shutdown if you get webbed.
- Damaging Auras and/or Traps stacked can exterminate the queen's spiderlings in seconds after they spawn, thus stunning the boss sooner.
