Treefell is a Heavy-weapon Attack-slot rune that drops exclusively from Cogah-mode encounters. Best farm: Sinecure-errant Vella (Cogah) — locate the Vella encounter, ring the Cogah bell to enter Cogah mode, then confirm the (Cogah) nameplate before committing keys. The Mendicant King (Cogah) is an alternate source but requires bell-summon access (~1 hour CD). Both sources are Cogah-exclusive — no Overworld or container source exists. The rune empowers charged heavy attacks: 100% faster charge, extended reach, and 70 Defense bypass for 8 seconds, with each kill resetting the duration. Pair with other Cogah rune farms if rotating between bosses.
