It's out of the Bestiary of Kynn.
-4 Int, -4 Wis, LA+1 if Tiamat can command you (doesn't cross interplanar borders), LA +4 if totally free (worthless unless you're invading Tiamat's plane).
You roll three times on the random quality menu, 5% chance of each or 20 different outcomes. 96~100 is roll twice ignoring the results above 95 so if you fudge the rolls you can roll up to six times (one series of double rolls per).
+5 Spot, +1 Claw, +4 Str, +4 Dex, +4 Con, +10ft Land Speed, 10ft Stinking Cloud 24/7, Frightful Presence, Claw Size +1, Slams instead of Claws, +3 Natural Armor, Scent & +2 Insight to Reflex, Energy Resistance 10, Fast Healing 3, Bite/Claws deliver 1dex/1dex Poison, SR 10+HA, +2 Dice to Breath Weapon, +1 Sorcerer Spellcasting, Blur 24/7, the double roll.
Obviously, additional casting is the best but everything is pretty nice really.
