Beyond Chaos is a Final Fantasy 6 randomizer that randomizes practically everything - character abilities, sprites, treasure chests, enemies, equips, etc. Every seed is different. The Permadeath part means that once the party is wiped out the game is over and a new seed is played. Generally, grinding is frowned upon. I finally completed the challenge on June 13, 2018, although it has a bit of an asterisk* beside it as I did not begin streaming it until I began descending the Fanatics' Tower. Multiple other people have completed the challenge by this point, but it's still pretty sick to do.
