Fungal bioluminescence, fireflies, glowtrees, a few fireflies in clearings, a few fungal lights in caverns, bioluminescence is red.
Coastal fog, visibility 40 feet.
Normal forest with clearings fairly numerous.
Storm, stray distant lightning, drizzles, hot winds.
Rivers are normal and there is morning dew, 33% more rain than usual for this level, one level down in river strength from normal.
Metal and rock unreliable, 67% decreased tensile strength for this level, ground can break (probably lethal).
If plants permit there is vine-thatching over smaller gashes, cavern entrances are fully crusted over, crust marginally easier to remove, vine-thatchings are brittle and useless.
Lightning causes forest fires, fissures and lava fields, forest fires stop at rivers.
