Rollem looks for messages that look like they are dice rolls, and then rolls them.

Complex syntax supported. See The V1 Syntax Docs for a complete list. @rollem help in chat for a quick link.

Roll without a label

You: 4d20
Rollem: 19 ⟵ [8, 7, 3, 1] 4d20

Roll with a label

You: 3d6 STR
Rollem: 'STR', 10 ⟵ [6, 3, 1] 3d6

Inline rolling

You: I [d20+5 swing at the orc] for [2d6+5 fire damage]
Rollem:
'swing at the orc', 15 ⟵ [10] 1d20 + 5
'fire damage', 12 ⟵ [4, 3] 2d6 + 5

Make some stats (4d6 drop lowest)

You: 6#4d6d1
Rollem:
16 ⟵ [6, 6, 4, 2] 4d6dl1
9 ⟵ [4, 3, 2, 1] 4d6dl1
11 ⟵ [5, 4, 2, 1] 4d6dl1
8 ⟵ [4, 2, 2, 1] 4d6dl1
13 ⟵ [5, 5, 3, 2] 4d6dl1
13 ⟵ [6, 4, 3, 1] 4d6dl1

Do some math

You: r6+6
Rollem: 12 ⟵ 6 + 6

Don't want prefix-less?

Set rollem's role to rollem:prefix:/literally anything to disable response to messages like 6d6 fire damage.
Now rollem will only respond to messages like:

• /literally anything 5d6
• I [d20 take a swing]
• @rollem 5d6 fire damage
