At the hydra lair. I’ve figured out you should take the sack thrown at you across the chasm. Then I filled it with the dust spewn in the mirror room. But I have no idea what to do with these ashes. I would have thought throwing them at the hydra would be the solution since the dust makes you attack yourself. Instead they hydras immediately attack me. I don’t follow the game’s logic there, but I think I’m onto something. I also notice you can scoop ashes into the sack. I think this will be useful to see the invisible demon in the cave room, but how I have no clue. There’s a graphical change for setting the sack on the stump so there has to be a reason for that, right?
