Drowning Beacon
Crossing a dreamscape of rocks and still waters, you emerge to face a sinking lighthouse emitting anti-light.
You can bottle up the eerily-glowing water that has pooled here or climb up the dilapidated structure to retrieve the lens.
Bottle
Procure Glowwater Potion.
Using a nearby bottle, you calmly scoop up the glowing liquid as the lighthouse peacefully sinks into the mud.
Good thing you weren't in there.
Climb
Obtain Fresnel Lens. Lose 13 Max HP.
You climb to the top of the lighthouse, unnerved by its steady sinking.
Upon reaching the lanthorn room, you start prying off the lens as the anti-light saps your vitality!
Finally, you wring it free; the lighthouse stops sinking.
