The Clarity Elixir

I see a thousand glimpses of the future, swimming in a chaotic blur. It is possible to focus my energies to see the true eventuality - the future most likely to come to pass. I will need an oracle stone to focus my power, and a special elixir to still my mind. To make the elixir, I will need the following ingredients: wing dust from Swamplighters along the river, fresh hearts from a monstrously-sized hydra, and a rare star lily. Meet me at Moonwillow Peak when this task is done.
