Im a lvl 26 warrior, i was in a group in a fort group killing sarnaks when one dropped.We all rolled for it except for the player holding the bracer,he just stood there feigning LD or something then switched off. About an hour later he comes back (probably hoping I had logged) but in the end i got it, and im glad i did.. its seems to be very rare and relatively valuable,im not sure whether im gonna keep it (been a few times i needed see invis.,mostly when dueling) or create a character who could use it.
P>S in reply to the lvl 22 warrior who wants to know whether or not to use it-i dont know what your wearing now but if you've got decent gear for your lvl (FS or crafted) stick with what youve got and dont drop the priorities,its a light bracer-you can keep it til needed if anything. And if you dont know already-DONT LOOT DURING BATTLE! its really an annoying, greedy little habit!
