...but it's been established the Rain and Dak have traveled together before. As such, I'm assuming they have, at least, a passing familiarity with one another's 'stealth skills' (which I'm guessing are pretty high compared to the rest of the party).... If so, I propose Dak and Rain scout the cave (minus the glowing top-knot, please).
I can write a little something up, if that's agreeable.
