With a +Dyson Logos
character sheet, and an image clipped from the web here is my Moldvay B/X character converted to Basic Fantasy. I believe the only changes between the two rules are an attack bonus for level, ascending armor class, and turn undead numbers are figured differently. Oh, I also claim 1d8 damage with my mace, another reason why I like Basic Fantasy!
Diagast has battled in the Caves of Chaos and survived Tower of the Stargazer in +Wayne Rossi
's B/X games, and now finds himself dimension hopping in +Joey Lindsey
's Flailsnails campaign.
I have a few other 1st level character I've rolled up and I've gotten in the habit of writing a new character according to B/X rules, Basic Fantasy rules and LotFP rules so they can jump into any campaign. Flailsnails is cool!
