Open-ended RM dice roll

[obiter]

I am sure someone has answered this but I cannot find the answer.
How do you get a d100 open-ended low on 5 or less and open-ended high on 96 or more, a la Rolemaster?
I can get it to do one or the other.

Our group are used to having RM Skills with a AD&D magic system so this would be really handy.

Thanks

I assume you looked at the wiki page? Not sure it's possible with chat die expressions, but if so, would be detailed here; https://fantasygroundsunity.atlassia...0/Rolling+Dice

Take a look at the MoreCore Ruleset. I believe it has RoleMaster dice available in it. You could probably pull out the code for those dice and put it into an extension for 5E.
