Reroll duplicates?

" Eye Rays. The mindwitness shoots three of the following magical eye rays at random (reroll duplicates)". How do I roll 3d6 rerolling any duplicates (rerolling until I have 3 unique numbers)?

You have to do it manually without the API, a pro subscriber perk. You could generate the total possible combinations of the possible values and then build a rollable table to randomly choose between them to get it in one go.  That could be quite the undertaking if there are more than a few options.  N!/(N-3)! rows.

I believe there are only 20 unique combinations of three different eye rays (out of only six different rays), so a rollable table would be pretty easy to set up. Replace the 1's, 2's, and 3's below with the name of the rays if you like. 123 124 125 126 134 135 136 145 146 156 234 235 236 245 246 256 345 346 356 456

Ah right! Order doesn't matter. =D  That should be pretty straight forward.

Yeah, cuts down the list quite a bit!

You can avoid duplicates between two of the three comparisons with this: [[1d6r[[1d6]]r[[1d6]]]] $[[0]] $[[1]] But there's no way I can think of to link the final two dice.
