You take a die (singular for dice, in this case it's six sided), you go to your stats and find which stats you need for an encounter or whatever, and the number that is next to the stat is how many dice you need to roll.<br/><br/>For example, if you are trying to persuade someone in the game to do something and your Persuasion stat is 4, you can roll 4 dice of six so 4d6 (this is the abbreviation, the initial number [4] is the amount of dice you can roll and the number of sides is 'd6' [six sides]) Then depending on the person you are trying to persuade, the number you need to roll collectively changes.<br/><br/>There is a dice roller on the site if you scroll all the way to the top and click "Dice Bot." Then, it is pretty much self-explanatory there, you put in the amount of dice, the sides, and roll.<br/><br/>You don't have to roll a die everytime you post, just everytime you want to do something that needs to be rolled on, like the Persuasion example above.<br/><br/>Memento Mori is Edgar's familiar, which is like a pet of some kind to put it simply.<br/><br/>And the confetti spell was being rolled. There is a number that she needed to roll to succeed. Since she succeeded, the spell worked. If it did not, the spell would backfire or something really hilarious. I have no idea what the number was that she needed to roll, but I think she got over 10 anyway so that covers most spells.<br/><br/>I think this answers your question? Maybe?
