Dices

Is there any description when to use the dices D100, Low, High and Open?

Hi Widukind,

In Rolemaster it really depends on what you are rolling for so you usually need to figure it out based on what is happening. Attacks are high open-ended. Criticals are either a d100 or high open-ended depending on if it is a large or super large critical table or not. RRs and skills are open-ended. I can't really think of a low open-ended and don't know if there are any since I don't think I've ever had to roll one. Maybe someone can let us know. ;)

Attacks, Critical hits - high open-ended
RRs,skills - open-ended
?? - low-ended

maybe someone can let us know us more

Only Arms Large, Arms Super Large, Spells Large, and Spells Super Large are the only high open-ended critical tables that I can think of. All the rest are a D100. Spell fumbles are high open-ended but weapon fumbles are D100. If there is a table involved you can usually look at the range of the table to determine what roll should be done for it.
