Dunedigger Spawn Mechanics

[Dawgrin]

Last night I was grouping in N Ro with a great group of people at Derv 3 and we had the pleasure of an unexpected visit from the Dunedigger. We were all even more elated when he dropped and left behind his shield!

I was amazed to see him, as in my 10 year experience with EQ I have only seen him once before, and at the time, all he dropped was a hide.
The more I thought about it, the more I realized that I had very little idea how this Ultra-Rare NPC's spawn mechanics work. As I searched, I found out that no one else really had any idea either.

Here are a few of the things I have heard...

1. He spawns only once per EQ year
2. He spawns once every RL 2 Weeks
3. He spawns after lots of little armadillos have been killed
4. He can spawn near the sunken tower in N Ro and can path around the zone
5. He spawns near Derv 3 and does not path

From my experience with him once years ago on Live and last night here on P99, I can say that in both instances He spawned near Derv 3 and did not path. Also, I did not see any other mobs spawn where he had, even after several hours at that location.

I would love to learn a little more about this...what do you all think?
