Walkthrough

 * The Terrorweb Queen spawns together with four Obsidian Guardians. All five foes can cast Ward Against Harm, and the Guardians additionally use Obsidian Flesh. Luckily, they spawn in an area with lots of cover, so you can easily avoid their projectile attacks and spells. (Beware of Meteor Shower.)
 * As the location of the quest is fixed, an excellent strategy is to fill the area with traps before taking the quest. If you concentrate them in one or two corners of the quadrangle, you should be able to take out at least one, and possibly two, Guardians right at the beginning of the fight. The Queen herself is too resilient to fall to this strategy.
 * After killing the Guardians on one side, you will have to run through them to the other side. Make sure that a Warrior (protected by Spell Breaker) has the attention of the Queen when you run through, or she can follow you to a location where the walls stop providing any cover.
 * Don't panic. This quest, although one of the hardest in the Underworld to get to, is one of the easier Reaper quests.
