Offa the Scout's Quest
Location: The zones east of Caras Galadhon, west of the river Anduin.
Quest: Find Offa the Scout, who sneaks around near the western edge of the river Anduin. He will say something about how his camp was attacked, and his friends slain, and that he wants his cloak back. Here the quest divides.
If you're evil, you can track down Coubhel the elven wanderer in this same area, kill him, and take his cloak back to Offa.
If you're good, kill Offa, and loot his key. Find a muddy sinkhole on the western border of the river Anduin; down from there (deadplants) is the chest the key goes to, and a tarantula that prevents you from looting it. Kill the tarantula, and loot the chest. In the chest can be a ring that casts bless when used, but has a limited number of charges, and decays once empty. You can take this ring to the ghost of Enidale, in a tomb all east of the Anduin, near the ruins in the northeast corner of the zone; he may reward you with a black metal wristband, but it's a semi-artifact, so if all are already in the game, he just gives you 5 gold.
Note: The black metal wristband is not worn by Enidale if it is loading. This does two things: prevents you from simply killing Enidale to get the wristband, and prevents you from being able to easily check whether or not all wristbands are currently in the game.
Note: It may not be possible to simply hoard quartzite rings and try for wristbands whenever you want. I had a quartzite ring that was a week or so old (had been used once), and another loaded for me; Enidale would only accept the new one. -Belamir
Hint: Disregard my hint about Offa not entering forest rooms, this seems to have been changed.
Reward: A golden quartzite ring (bless when used, self only, limited charges), or a black metal wristband (+2 OB while worn), or 5 gold. If you do the evil version of the quest, you get a grey fluid sack.
Extension: Bring the ring to a shadow in a tomb on the other side of the river. This can give you a blackened wristband or something like that which fiddles with you ob/pb/db bonusses.
