Here is an example how it's done in Elisp only.
Hey, never to late to return to the old pen-and-paper RPGs!
Actually I don't want to do that ...
;;; -*- lexical-binding: t -*-

;; this file:

(require 'cl-lib)
(cl-defun dice (&optional (sides 6) (num 1))
(let ((sum 0))
(dotimes (_ num) (cl-incf sum (1+ (random sides))))
sum) )
;; (dice) ; 1D6, 1-6
;; (dice 3) ; 1D3, 1-3
;; (dice 3 2) ; 2D3, 2-6
