Hello.
Go to a raidboss with any friend. Say, AQ... Have atleast a good skill (79 GH on retail, so focus death (no CW yet... wtb sp) hehe). Power up with focus death and any other skill you have. Get in a duel wiht your friend. Once you're in the duel, go behind the RB and backstab it (with VS on preferably). You will get raid-cursed, but when the duel is over, you're fine. This is because when the duel is over, you lose any buff and/or debuff that was given within the duel.
Keep on doing this until it's very low hp (shouldn't take long) and then leave with the high-lvl character. Wait until looting rights are off, and voila! Your lowbie/lowbies can kill the rb and get full drops (if the looting rights are correct, anyway).
PS: Not 100% sure on the drop thing. I've only tested it on shitty low-lvl rb's. They DID drop items though.
Works on official L2 servers. Tested on Luna.
EDIT ADD: Have done this to do sub-class quest RB cabrio, although we were many 78+ people.
