Hello Oreki,
I would propose to change the turn-in follow-up for the quest "Tripatriate Union's Feud" to 2 items (e.g. Mystic Horn) instead of 5 for the rewarded consumables. Currently, it's 5. In classic, it had been 5 as well but got later changed to 2. That would be a harmless quality of life adjustment imo. Alternatively, the rewarded consumables could be added to the Tool Dealer NPC.
