Normally, Rollem does not use a prefix. If it looks like a roll, Rollem will treat it like one.

Prefixing
If you don’t want this behavior, give Rollem a role of rollem:prefix:<your prefix here> to disable no-prefix rolling.
With this role:
- Rollem will still roll lines prefixed with
&orr - Rollem will still roll lines addressed to him.
@Rollem 2d20 - Rollem will still roll inline syntax
swing the sword [2d20 for justice] - Rollem with not aggressively parse lines
2d20 for justice - Rollem will aggressively parse lines prefixed with
<your prefix here>
