METTLE Dice Roller

A dice roller for tabletop role-playing games using the METTLE Core engine and variants:

• METTLE Core
• Mutananny

As a brief explanation, METTLE Dice only count the 1-3 faces for adding up the Score. Edge is the number of blank (formerly 4-6) faces, revealing the power or effect of a roll. A Twist is offering up a narrative complication in exchange for a reroll of all edge (blank) dice. It's explained much better in the games above.

This roller goes up to 18 dice, after that it gets crowded.
