Roll dice with any number of faces and get every roll plus the total. Uses the platform CSPRNG with rejection sampling, so every face is equally likely - a plain modulo is biased.

Uniform random integers in any range you give, with or without repeats. Rejection sampling, so the ends of the range are not slightly less likely - which is what happens with modul
