Ok, let's look over this:

1 - Relic: massive amounts of RNG involved.
2 - Raiding: RNG involved.
3 - Triple Triad: RNG involved. (Random rule trololol)
4 - Chocobo Races + Breeding: massive amounts of RNG involved.
5 - A lot of Vanity items such as ponies: massive amounts of RNG involved.
6 - Master Crafting: RNG involved.
7 - Fishing: massive lolroflhahalmfao amounts of RNG involved.


What does not involve RNG in this game? Trash dungeons, trash crafting and botanist/miner.
