Walkthrough

 * The Terrorweb Queen spawns together with four Obsidian Guardians in a small passageway. the Guardians use Wards to defend themselves and the Queen from anyone who comes near. however, you can easily use spells that does not require a line of sight, to target them, one by one, from behind a wall. note that the Guardians use Obsidian Flesh. look for it and wait for it to ware off.
 * After killing two Guardians on one side, you can teleport to a Reaper in the other side, to attack the other too in the same manner.
 * 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.
 * Don't panic. This quest, although one of the hardest in the Underworld to get to, is one of the easier Reaper quests.
 * The Queen or the Guardians use an unknown skill or ability to knock characters down.
