Dices are nice little entropy generation devices. I used dices and recommend using dices.
BUT: you really must know what are you doing and how you are doing it.
Just to do a coumple of examples, there is a risk of exposition/vulnerability if you use a software tool like iancoleman's to derive words and addresses on a connected or infected device. Also you can be exposed if you write on paper the dice rolls or if you take a pic of the software tool screen showing the words as reference to engrave on metal.
So roll the dices, but be careful and think carefully at what are you doing.
