I will make all the effects available as ULX commands in the next release.
I feel like if users could select their own effects, that would defeat the purpose of the addon a little though. 
A rocket effect is already included since I first released this addon. You can add this snippet of code to add 'banning' as an effect. 
Ohhh. An explode effect would be very evil! But... the dice is evil. 
1. Adding a ban (maybe kick) to the roll would be scary as <censor>, but I love it. I would fear that users wouldn't be so excited to use it though considering they'd risk losing their score and karma (not touching configs for these), so I don't plan on adding this effect.
2. Adding that explode option would be dope a.f. lol I'll read through this again to figure out how to add that. I'll also check out ulx jail to the mix, now that I think of it. Or even get whipped by the dice (ulx whip/slap). <censor>, options seem to be endless once you know what's going on lol
3. This shouldve been 1 but no ragrets, but I understand the purpose of it being random and not being able to choose the effect. I just think players would enjoy the option to some effects that aren't normally accessible at their own leisure. Similar to ulx Fun commands. I'm mainly talking about the drugged and confused effects. Giving users the option to do this to themselves has been a popular request. For now, I'll look into extending the time lengths for some effects.
UPDATE: Also, is there a way to move the timer configs for all effects in the RTD to the top of the file? I don't mind scrolling down changing values, but for the sake of convenience have a line for each effect and selecting the value at the top of the code. Just a suggestion.
