This is an item related to the first Variant Dungeon, the Sil’dihn Subterrane. Using the Ballroom Etiquette – Ample Appreciation will reward you with the /wow emote.
To obtain Ballroom Etiquette – Ample Appreciation, you need to first unlock Variant Dungeons. You need to have a Disciple of War/Magic up to Level 90 and have completed the main scenario quest “Endwalker”. Once you’ve done that, first talk to Osmon in Old Sharlayan (X:11.9 Y:13.3). Then you can pick up the quest “A Key to the Past” from Shallow Moor in Old Sharlayan (X: 12.0, Y: 13.3).
Finishing any boss in Sil’dihn Subterrane will reward you with Sil’dihn Potsherds. Every run will leave you with 3-4 Potsherds. These can be turned into Trisassant in Old Sharlayan (X: 12.0, Y: 13.3). Ballroom Etiquette – Ample Appreciation costs 9 Sil’dihn Potsherds.
