I've killed Bowlord Rorn 4x now, and have gotten cloak once and veil 3x, and zero glove, so its not that common. The Kyv bow is called A Broken Kyv Bow, and drops off the Kyvs in his room, as well as in other parts of the zone. My guess on that drop rate is about 1:20, from eyeballing it and my own run on luck.
Red to lvl 67 (most likely lvl 70 like the rest of the new dragorn model mobs that were added). Glares threateningly but does not attack when hailed (I have low Mira faction). Does not attack. Most likely a quest or NPC mob. Northwest corner (next to castle) on the east half of the zone (castle that goes to Noble's Causeway).
