Information:
Basically a dragon that doesn't cast fireballs, but they do enough damage with their claws, have deadly poison, seem to be faster with the UO:R patch and their pathfinding is excellent. On the bad side, the loot is ridiculous so I wouldn't even bother with them. One thing of note: they have some of the coolest shades red and brown (I have seen a brick red one and a purple one) of any of the Dragons (besides the White Wyrm). Too bad you can't tame them. I take that back. A Deadly Poison creature for tamers? Eck.

How to kill:
Shoot it with your bow or blast it with spells until dead. Trapping is hard but doable. There are 2 spots here and here on Titan Beach in T2A. If you get it trapped, drop a Blade Spirit and watch it die. Just beware of all the spawn around you as well.

Loot:
200+gp, chance of magic items, chance of a level 3 treasure map, some reagents. The loot on this guy should've been upgraded. They are harder than some monsters that have more loot.
