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 ...

(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
