Valor - A reimagination of Bravery mode
I disliked Bravery mode because the monsters you get in your chest are not truly random, they are tied to the area of the chest. This means that for example the Underworld chest can only give you a monster that spawns in the Underworld. Randomizer has the problem that it breaks progression too much (get an early Moccus spawn and you can farm Hide+5 and never die, or get an early Mad Lord for infinite Shift Stones), so I don't like that one either.
Valor is a mode on top of Bravery that randomizes monster chests, so they can spawn any monster. There is some logic in place that will guarantee that you can finish the seed, which means beat Mad Lord, access all areas to get the monster chests and beat all champions. Other than that, the monsters you get are random (although, as in vanilla Bravery, Spectrals can only be granted in Eternity's End). I tried to stick to roughly the same progression logic that the devs had in mind, so you cannot start with a monster that has Improved Flying or Swimming. The Caretaker of Sun Palace will give you a swimming monster.
Valor uses the UnityEngine Random method for all random calls, so as long as the configuration files are the same, you can still share your seed and play along with others.
