6hp? Did you have a familiar?
Original D&D has d6 HD across classes, and I use the house rule of starting off 1st level PCs with maximum HP. (You can shave off my chest hair and burn my OSR card if you want!)"Ruthless hedge-wizard" is right. Sculdge was tormenting whimpering goblins all night, and even let poor Farmer Filby take a knife in the chest for him! ;)
Few things I love more than seeing these old-style character sheets filled out in smudgy pencil.
Hit Dice for Magic Users is 1d6-1 though right? HD for Fighting Man is 1d6+1. I really like the character sketch. It just screams "failed cultist".
