Okay, I did a couple quick die tests. I think my original orange die knew it had to put some effort into it, and I'm a little surprised that it beat out the glow dice and the copper one, despite my initial test rolls. When I unboxed the new dice, I rolled a handful of times, and they all rolled rather well, with several nat 20's in a row on one of them. So this time I marked down what each die rolled, and totaled the numbers of ten rolls together.

My original cursed orange plastic die: 89 (the only double digit rolls were a 17, two 15's, and an 11)

Glow metal die: 81 (dude, what happened here? You were doing so well earlier! The highest I rolled were two 16's)

Copper die: 84 (again, I'm a little surprised by this outcome. Got as many double digit rolls as the plastic die, but the highest was a 13.)

Gold die: 141 (with two nat 20's to boot! This one had by far the highest rolls, with only three of them being in the single digits.)

I think I know which set I'm gonna roll with for the most part!
