Could you add a roll that accommodates the specific RoleMaster Open Ended d100 (aka d100OE)? It works as follows: An open-ended roll means that there is no absolute minimum or maximum. First make a 1-100 roll; a roll of 96-00 indicates that the dice are rolled again and the result added to the first roll. If the second roll is 96-00, then a third roll is made and added, and so on until a non 96-00 roll is made. The total sum of these rolls is the result of the open-ended roll. If the first roll is a 01-05 the dice are rolled again and the result subtracted from the first roll. If the second roll is 96-00, then a third roll is made and subtracted, and so on until a non 96-00 roll is made. The total of these rolls is the result of the low open-ended roll. A roll of 01-05 on anything other than the first roll does not cause one to roll again. It is possible to add this as a potential die roll?
