How would you make a dice mechanic more interesting
So if you roll a d20 to see if you hit an enemy and a d6 for damage. How would you take a simple mechanic like that and make it more interesting? I was thinking of a game where the player gets a range of d20-d4, and once they use the d20 to see if they can deal damage, they can't roll it again unless they either defeat the enemy or some other way. But I feel like the dice mechanic can be a little boring after a while, so I've been trying to think of unique ways. Maybe after defeating an enemy one of your dice gets a power boost or maybe you can change the effects of a natural 1 to be almost like a natural 20, but idk if that would be fun
