Explosive dice? Fail to make a roll in 90 seconds and kapow!? lol Keep it light, its entertainment.
Oh, man, would I buy several sets of those in a second. Anything to stop people from dice fapping. If you shake it more than twice, you're just playing with yourself.

And that wingnut who figures that he's at the craps table and rolls that nearly spherical D20 like he's just bet the load on a hard eight. Dice and minis go flying everywhere! We actually had to get a rolling box for this guy so that he could roll without every third try resulting in a five minute search under the couch and desk for the missing dice.
But, if you think that Elementalist is bad, the one that takes the biscuit for me is the 3e 4th level dwarf fighter with an axe taking over ten minutes to take his turn. Repeatedly. Unfreakingbelievable. It was an online game, and if someone would invent a way to stab someone in the eye over the internet, I'd give him a kidney.
