Sorry for the double post!
Okay, so theater of the mind can be fun, but at times it can be dangerous. (Looking at you, hidden elves shooting me full of drowning!)

This is
atrocious, but nobody ever said I was an artist. This is my understanding of the cave network right now.
We start with the entrance with the horses, through bear trap water junction, into the sand palm. There we have five branching paths, one of which has a secret hidden spicy spot (that's the black dotted line). This spicy side path leads to the zipline (the brown dotted line) which fords the water that otherwise cuts off the five fingers from reaching across to the frowny face bandits. The frowny face bandits are also not looking at the ring finger, the fourth tunnel from the sand palm, so Yatari is able to emerge like a bat out of hell and poorly execute an eldritch blast with the element of surprise.
With any luck, that means Davor can then zipline down and hit 'em with a "scythe to meet you!"
