Asabi
Asabi are a race of savage, dim-witted, warlike lizardfolk native to the deserts of the Forgotten Realms. They come in two species; the common asabi, and the much larger (and duller-witted) Stingtail, named for its prehensile tail armed with a venomous stinger. They are most common in the Anauroch desert.
Stats for Asabi first appeared in the Advanced Dungeons & Dragons splatbook "Anauroch", before being reprinted in "The Villains' Lorebook" - stingtails instead appeared in "Elminster's Ecologies". They were updated to Dungeons & Dragons 3rd Edition in "Monsters of Faerun", with expanded fluff being provided in "Serpent Kingdoms".
