PDF Interactive Character Sheet

Here is a PDF character sheet that you can actually fill out. It's from the Atlas-Games Web site But I'm tweaking it a little.

Noncombatant, Virtue

Characters who take the Noncombatant Virtue may not learn any weapon skills. All grogs start with the default Ability Brawling 1 and may keep this Brawling Ability at level 1 but not raise it. The character may not exchange another Ability as a replacement. A specialty of dodging would be appropriate for a Noncombatant.

Playing Characters

Who Plays What?
Wizards and Companions will only be played by their creating player. Grogs can be shared among all the players depending on the adventure (i.e. there may be adventures with only one wizard or no wizards). You should try and play a grog within the parameters set out by the grog's designer.
