i have killed him 12 or more times by now and its pretty safe to say all of the mobs that are always 'a shissar necromancer' are his PHs have spawned him from the stationary one by the portal a roamer on the first floor in the western section the roamer that paths to the portal a roamer on the western half of the second floor have farmed him long enough for 4 charms and its about a 1/3 drop rate for the charm only once or twice did he not drop a castaway bracer and think he drop minor essence twice and lesser 3 times was simple to kill on a lvl 101 SK with TDS and CotF group gear and was just as easy on a 103 necro geared just as good as the SK pet on the necro is wearing dimensional warrior armor and TDS crafted jewlery hope this helps!
