Day 12: The Hollow Grove
Day 12, “The Hollow Grove”, is the 6th day in Whisperwood. It happens at dusk with fog weather, and 38 enemies march in over 4 waves. The battle lasts about 3:45 on Normal.
Captain Bramble says: “The trees are whispering... Old Mother Hollowbark is awake!”
Foggy! We can't see far. Watch closely.
What it looks like
Dusk in the Hollow Grove. Fog rolls between the roots, and a giant hollow tree with a swinging lantern fills the right edge.
Weather: Fog
Enemies beyond 55% of the field show only as silhouettes with no HP bar, until they come closer or step into torch, Lighthouse, or fire light. Gloom Wisp and Mushroom Shaman glow through fog. Flyers are above it and always visible.
Foggy! We can't see far. Watch closely.
