OK, time to get this big boy moving.

to provoke discussion, here is some chiseled down information from the above posted document. Let’s see how we can use this to reconstruct him from the ground up.
According to the original DDG, Maglubiyet is an 11-foot tall, black goblinoid “with red flames for eyes, sharp fangs and clawed hands.” He is the god of war, commanding mighty armies of goblin spirits as their general. In this book it states that the eternal war with the orcs goes on in the Nine Hells (Baator). He rules the rest of his (as-yet-unnamed) pantheon with an iron hand. Notes on stats:
2 attacks per round, 2d10 damage each (is this with his axe?)
Stats: Str 20, Int 19, Wis (hmm, it says 77, but that must not be right), Dex 20, Con 22, Cha –2 (this was a factor of 1E I suppose, given its ultra-humanocentric nature.)
HP 350
Class levels:
10th-level cleric
16th-level fighter (well, as 16+ HD monster)
6th-level illusionist
10th level assassin
psionic powers of VI level (need to reference my 1E books for this one)
Monstrous Mythology introduced Mags and a number of other old and new gods to 2E. his appearance and attitude was pretty much the same, but there were new stats to accompany rules changes and the like.
2 attacks per round, 2d8+4 (his +4 axe) +7 (strength)
Stats (a little different): Str 19, Dex 17, Con 18, Int 15, Wis 15, Cha 19
Movement rate: 12 (would be 30 ft in 3E)
Size: reduced to 9 feet tall in this version
20 HD, 160 HP
class levels:
16th level fighter
12th level priest (cleric)
also:
can project burning hands (16 hp damage) 1/turn; haste himself 1/day; speak unholy word 1/day.
Death throes: explodes in 10 HD fireball.
+4 axe: huge, bloodied coal black axe which has the property of a sword of sharpness.
Planescape also featured a wealth of information on gods and godlike beings. That series did not deal much with physical stats, but instead presented information on the god’s nature, realm, and followers. Planescape transplanted the goblin gods from the Nine Hells to Acheron, giving them their own special cube, Clangor. Otherwise, he’s basically the same as the old version, but much more expanded. I’ll figure out what Planescape info needs to go into his description.
I’ll also need to take a look and see what information I can garner from the original MotP.
