d20 - an RPG dice roller
d20 is a Mac tabletop dice roller with formula editing, modifiers, simultaneous rolls and grouped reusable presets.
Pick for reducing repeated dice-entry work at a tabletop session.
Saved formulas and keyboard shortcuts suit recurring attacks, damage and game-master rolls.
Keep in mind: It is a dice tool rather than a full character manager. RANDOM.ORG integration is described, so do not assume every randomness feature works offline or supplies certified gambling results.
