Press the rubble to gain an Enchantment Rock. Find a pickaxe in the chest located in the west corner, and pick the enchanted rock and then collect magic dust. Keep climbing up the ladder and after that, climb another ladder. Fill the vial with Water of the Ancients. Add the magic dust, and you have the vial of Magic Water.

Now, mix your herbs in the same order they are in the scroll. 3 Sunbleached herbs and one Sunset Herb. Ground Sayaniona's Horn. You will get a vial Enchanted Posion.
