FFXIV: Endwalker - This OST Theme Deserves More Love
Not sure what the title of this theme is called and we probably won't know until the official soundtrack is released. But I've loved this theme for a long while as it's been used in the Reaper reveal trailer as well as at the start of the Endwalker Job Action trailer. I wish that this theme would be used more often in-game, and would've made for a great dungeon boss theme.
