Equipable, Equipable Relics

Original
Equipment/relics characters can wear are unmodified.

Random (-ier, -ierr)
Equipment/relics are equipable by a random number of characters within given range selected using a uniform distribution. This option can potentially result in large variations in the number of items each character can equip.

Balanced Random (-iebr, -ierbr)
Equipment/relics are equipable by given number of random characters selected using a uniform distribution. The total number of items equipable by each character is balanced.

Original + Random (-ieor, -ieror)
Characters have a given percent chance of being able to equip each item they could not previously equip. If given percent is negative, characters have a given percent chance of not being able to equip each item they could previously equip.

Shuffle + Random (-iesr, -iersr)
Shuffles the inherent equipability pool of each character between the characters. After shuffling, characters have a given percent chance of being able to equip each item they could not previously equip. If given percent is negative, characters have a given percent chance of not being able to equip each item they could previously equip.

For example, Locke's equippability may be assigned to Setzer, and Setzer's to Relm, allowing only Setzer to equip Wing Edge (in vanilla only Locke can equip Wing Edge). However, Setzer will no longer be able to equip Fixed Dice, but Relm will be able to (in vanilla only Setzer can equip Fixed Dice). Equippability is applied on a per-character basis.

Note: Gogo/Umaro cannot remove the curse.
