Dodge through the flame spitters at the entrance (or wait for the pause), and avoid the red circles (spike traps) at all costs, killing the oozes as you reach the inner crypt. The spike traps can take away half of your health (around 2000 damage).
An elite cave spider nests in the treasure room's antechamber, complete with spider eggs, numerous spike traps and the locked doors which lead to the treasure chest. If the spider is at its normal position (not near the entrance), it is possible to carefully reach the doors without being attacked.
Hermit Guilland, a norn NPC skulking at the entrance to the crypt, suggests breaking the spider eggs before they hatch. This is supposed to let you get rid of the adds during the fight with the elite spider, but it causes the elite to attack. Instead, take the small right turn after her chamber, kill all the spiders within, drop two boulders on the pressure plates (north plate first) found there. This should open the locked door to the chest.
In order to advance to the treasure room, you must kill the elite spider in addition to triggering the pressure plates. A Mysterious Rock can be found near the chest, which serves as a quick teleport to the exit.
If you decide to solo this not very difficult elite (although it is an elite, after all), the eggs will hatch every now and then and cave spiders will join the fight (around 6-8 spiders in the last wave). Fighting at the room's entrance is a good place to avoid the traps and to see the adds coming. A good AoE damage skill, as well as healing and poison removal are useful, as well as a pet to keep the boss's aggro, if available. Be aware that the spiders at the entrance to the elite's room will respawn as well, after a while.
- The Gloominator required for the Twilight III: Dusk collection can be used anywhere in the treasure room at the end.
- Mounts can be used to avoid a majority, if not all, of the floor traps with some careful maneuvering.
- This crypt is the location for the personal story mission Dead of Winter, where sylvari characters who have chosen to join the Durmand Priory venture into it with Trahearne to defeat Mazdak the Accursed, a powerful Risen that claimed the life of Riannoc.
