I wanted to make my own character sheets, as there seems to be an unusual bias towards female characters.. female cleric, female rogue, female paladin, female barbarian!? I'm not sexist, I just can't get lost in a role playing elements of a game as a female character. Anyway, I wanted to change the artwork and background text so I could enjoy the role playing elements more. I just opened the PDF character sheet in Acrobat Pro, saved a copy (which strips most of the important security controls) then opened that copy in Illustrator where the layers can be easily edited. It's then a doddle to change what you want to. I had to build a replica single character token card to match, but that wasn't too hard (It's just a green border and a textured background. I printed both out on 300gsm card which is very nearly exactly the same. Then, as you keep the decks in the box, I cut out the left panel of the character sheet with all the stats on, which made a really handy character sheet that you could hold up.
To be fair though, there really should be an online character creation program. This is supposed to be a role playing'esk game, players should be able to make their own characters and the game should support that.
