I found one just west of the spawn point on the Map, near the water. I guess they either spawn in an area near the spawn point on the map or something. Night last long enough just search the entire valley there and you should find one.
The correct skeleton is the Crumbling Skeleton from Avalia starting area where the Mage Tower is. I killed Shambling for an hour no bone. I went over to the Mage Tower and killed 2 Crumbling and it dropped.
The 2nd spawnpoint got removed with the map update on Feb. 13th. He still can spawn in the tunnel on the northern side of the dragon mountain at 2870/2160
These are a great mob to farm for a squishy, or if you're a pet class barely paying attention. They seem to rely on auto attacks for damage, and they just attack for like 1-2 every 2-3 seconds, a rogue could comfortably tank these

really powerful spell. At lvl 18 I'm easily doing over 500 damage in a single cast. WARNING: Make sure your fire, cold, and shock focus replenish utilities are recharged. Once you cast this spell at full effect it will eat all 15 widgets of your spell focuses. cast your three fire, cold, and shock focus utilities to instantly replenish and you are good to go.
Farmed a 2nd one for my wizard. Farming took 3 hours on Feb 1st, 6 hours Feb 9th, 3 hours Feb 11, and finally 5 minutes Feb 13th to get a second one 12h5m. Didn't pay attention to what mob dropped it. GOOOOOOOD LUCK! keep sane!
