For Rogue quest:
You go to Tower of Wailiing Wind. Near the entrance, you head off to the left, to where the tombstone is, that gives you the quests inside TWW.
There you talk to an NPC who gives you a quest. The quest has you retrieve documents that are surrounded by small floating exploding golems. If you get too close, they go off, and 1 hit you (no durability loss or exp/tp debt).
The key is to use hide, and try to sneak past them, retrieve the documents, and bring them back to the NPC, before time runs out. I believe you have 45 seconds to do it.
