Support Items are usable during battle only. They are a one time use item, and you may not use more than one item at a time. They are independent from Special Items and thus can still be equipped even if Item is set to off. Support Items have no influences in-battle, but it has an effect on the aftermath of the battle.
All Support Items are AP items buyable from the Antiques Dealer, but some can be obtained as reward from musou board, or randomly get crafted instead of what you want to craft. There is also a chance that you may get some of these as an item reward from descending Kunlun Mountain.
