"Reserving Instance"

[Kenka]

HM Ifrit, Garuda, and Titan all drop only weapons, but are also part of a relic weapon quest that gives you the best weapon in the game, so sane people only ever defeat each of the HM primals once (and then only ever go back when an acquaintance needs their quest completed).

Just a FYI, people go several times to Ifrit and Garuda HM to farm their weapons..
