Dice Tray

The Dice Tray is where one goes to make a roll in OMM! Alternatively, if your controlled character's Sheet has preset rolls, you can skip the Dice Tray and roll directly with Ctrl+Clicking the die icon wherever it appears on an opened Sheet.

Sum
Adds all dice and modifiers together. (D&D style roll)

Max Roll
Takes the top result of all dice rolled (Forged in the Dark style roll)

Min Roll
Takes the bottom result of all dice rolled (Unskilled Forged in the Dark style roll)

Modifiers
You can subtract or add to the basic roll - for example, if you're playing a Powered by the Apocalypse game, you will want to select 2d6 at the bottom of the die roller, and then add or subtract a Modifier equal to the relevant Stat. You can add multiple modifiers, and OMM will do the math for you!

Dice
You can add dice of any number of sides - if it's not listed, select DX and manually enter how many sides you want. Each click adds one die of that many sides.

!!! Bug Alert: Currently nontraditional dice (anything other than the regular d4, d6, d8, d10, d12, and d20) appear as a broken image in the dice tray. The roll will still work, though!

Roll Dice
When you're done, select Roll Dice to see your result - it will appear over your Character's head as well as in the Chat log.

Custom Roll Types/Dice
You can somewhat automate roles using Sheets, Role Types, and Dice Editor, though these features are still being worked on.
