Somebody has probably already done this, but I figured I’d do one just in case. Or, at least, for my own needs. So here it is – a form-fillable character sheet for Labyrinth Lord’s Advanced Edition Companion: BoL Classic Edition GM Screen (2854 downloads)
It’s the official sheet available from the Goblinoid Games website (here), just done up with fillable fields. Enjoy it in good health!
