Every character in your party needs strong equipment to grow stronger, but the best gear for each Vocation class varies. Nearly every piece of equipment is restricted to which archetypes can use it.
Some items may have strong effects that support a Vocation's strengths, while another may simply be the greatest buff to that class' offense or defense.
One party member is capable of wielding five pieces of equipment — Weapons, Armor, Shields, Helmets, and Accessories.
You can only have one item of each type equipped to a single character at a time, giving you limits on your party's customization.
Depending on which Vocations in you have on your team, you have a chance to use specific equipment restricted to the classes you've recruited.
