Ascension

Collect 2400 Essence total - the Seer's final threshold. Reach it and she thanks you, hands over her last reward and ascends, leaving the Resting Grounds. That means clearing essentially every Whispering Root and Warrior Dream in the game, so it's the bulk of the essence grind. Dream Wielder and a planned route through the roots make it less of a slog. Contributes to Pure Completion.
