Fun guy, we killed him on Pendragon a few nights ago for the first time along with the other 3 princes. They drop between 4 and 6 items each time all of 94% quality around level 49-50. The 50 drops are the rare ones. Of the 3 princes and the 20 or so drops we got, I think we got two level 50 items. The albion prince is a tank and is tougher than the midgaard prince who is easier but has 2 pets. The hib prince is the toughest as he tends to resist spells more and has 1 pet. Easiest way to take them is to logout pull each monster from his throne area, one at a time. Otherwise its a tough fight. Usually 3-4 inq types and 1 earl are in his throne area. About 2-3 good groups can take him down.
