I am working on a custom ruleset that utilises variable dices & dice pools. Basically, the way the system works is that when you roll for a skill, the player starts by selecting a dice between a 1D6 / 1D8 / 1D10 depending on the risks he is willing to take. He then adds a number of bonus dices depending on the naration. I would therefore like to know the following things: 1. Is it possible for the API to open a custom form where the player would select the dice he is rolling and possibly the additional dices he can roll. I would also need to provide to this form some data as the number of Bonus dices is based on the character's attributes. It would be nice if you could click on the attibute in qquestion in the character sheet and open a pre-filed form. 2. Can roll20 handle custom dices. I can live without the 3d models. All I need is to have the output in the chat.
