A ranger friend and myself (NS) have killed him twice so far hoping to get his bow. The first time he dropped only money and a sell gem. Second time he dropped money and a lvl 40 ROG cloak that isn't too bad.
He seems to be, from what we've seen, on a very long repop timer. After killing him the first time we waited around for close to 2 hours and he never spawned. 24 hours later, he was up again.
When he is aggroed, he doesn't attack or move from the tower, but he shouts, causing any and all nearby sylvanshades to aggro on whoever has his attention. What we've found works well is for ranger to shoot him with bow from max range on nearby hill, keep shooting until adds arrive, then turbo and lead the adds on a chase toward Necht. While that happens, I stealth up the ladder to finish him off. Seems to work well.
