From Allakhazam:

Monks of the Whistling Fist: It is likely that you need to be a tailor to
do this. Brother Qwinn in Southern Karana seeks the return of the code of
the whistling fist, which was stolen by him. It is dropped by Targin the
Rock, a rare spawn in the Sol B throne room. Bring him the Code and a
purple silent fist headband and you will get a special needle. Brother
Zephyl in Rathe Mountains wants the Idol of Zan Fi, which is in the
possession of Brother Raster, who spawns in the Mino Elders room in Lower
Guk. Returning this Idol, plus a red sash, results in a special tailoring
pattern. These two items need to be combined in a sewing kit with a swatch
of shadow silk (tailored) and a Scroll of Jonathans Whistling Warsong, which
is bought from the Bards Guild, to make a monk only item called the Robe of
the Lost Circle.

stats:

AC 12
STA +5
AGI +5
HP +25
WT 0.7

Looks like a maroon caster robe.

This is a very long quest. The items droped are no drop and ALL ALL, so some
players can loot it not knowing it is a quest for monks. Especially the
idol, that has stats in INT and WIS.
Targin the Rock seems to be a once a day spawn, may be even more often. But
Raster of Guk is the big part, a once a week spawn. Yes, once a week !!!!!
The brothers in SK and RM seem to spawn every 6 hours, and they disappear
after one hour or two.

I would say it is a lvl 35+ quest.
