isn't it a nightmare? it's dark and was at least made with a lot of heat, so it's stats would be a bit higher, i think something like: -1 CON(+2 against fire), +3DEX, +1STR, +2WIS
If its a nightmare replace the +2 against fire with a +2 against psychic and we're good. I'd say cosplay Oblivion's nightmare and make them not die but....
