I wanna thank you very much bros. The tips on how Duviri keeps the same rotation of equipment + Decrees helped a lot in farming Tarsome Extract and Rune Marrows for Oraxia and the new weapons.
I rolled a 24 horus Resource Booster in the Baro Gacha and quickly captalized on a Bountiful Harvest to farm 4x what I would normally. Got enough for 2 Oraxias in no time.
It also helps that the islands near King Palace in Oraxia's operation always come with a bunch of Kovniks.
