ToME WikiThe entrance is located next to the Barrow Downs (the yellow '>' not the purple one) to the West of Bree. You may wish to wait until level 30 before attempting the quest.
The quest level is small, and comprised of small areas separated from each other by hard stone, and connected by jump-gates. The entrance takes you to the top left corner of the level.
Monsters: Wights of various types occupy each small area, and there is one unique monster, The Wight King of the Barrow Downs.
Tactics: It is best to finish off the wights in each area one by one, then rest and heal up before moving on to the next area. The Hold life attribute is recomended for this quest, or some means of restoring experience such as potions of restore life levels.
Alao, do NOT kill the Wight King while on a jumpgate or jumpgate exit, as you will be stuck on the quest level. http://wiki.t-o-m-e.net/GeneralDiscussion/Stuck_in_Wight_grave
Once you have killed the Wight King, return to the mayor to complete the quest. The reward is the filthy rag of the Wight, which always makes you vulnerable to fire and either increases your mana or your spell power. The mana and the spell power versions are equally likely and it is pure chance which you get.
