You spend your Glory in the Hidden Teahouse. It's the slowest method of collecting Glory by far, but it's also nice to claim your share when its there. Every week, once you have joined a clan, you can claim some rewards based on your efficacy and participation in the Clan Battle as well as if your clan won etc, not sure the specifics exactly but you get a nice big chunk of Glory from it, I got 18,000 last week.If you have a lot of said item, it can be a good way to gain some Glory in a short time, but it's usually not very feasible in the long run. Once you have unlocked the Hidden Teahouse and joined a clan, you can donate various items for your specific clan that they request, such as arm guards and spears, and receive rewards in return as well a small payment of Glory.One of the best missions is the last non DLC main mission, because you get two immortal NPC allies with you who attack summoned revenants with extreme prejudice, letting you slaughter them enmasse with little effort. Some small missions that allow revenants to spawn are ideal farming grounds, such as the Bridge of Bone mission. It's slow going, much slower than co-op missions, but killing every Revenant you come across will add up eventually - especially considering the gear drops you'll be earning too (which can be donated for more Glory if your clan needs them) If you are in a white clan and kill a revenant from a red clan, you also gain bonus Glory (typically around 100%) which can lead to high level revenants giving you around 300 each. Spawning and killing player Revenants grants you Glory relative to their level and aparent difficulty, typically increases the higher the mission level also goes, to a cap of around 300-500.This is the best method of collecting it quickly enmasse, but naturally also requires the most effort. Joining co-op games and surviving through to the end so you don't get hit with a 50% or 25% penalty to the Amrita and Glory you earned, typically nets you anywhere from 500 to 4000 Glory depending on mission length, shrines visited, and bosses/amrita earned.Four main ways to get Glory, from most to least efficient:
