It's Spectral Sirup. I think you'll have to study about Heat Occisia at home then go speak to the Lizard Priestess, so she can tell you how to make it (1: Angel Leaf, 2: Red Pulp, 5: Water Lilly). Then you can make Spectral Sirup (1: Blue Pulp/ 2: Heat Occisia/ 3: Red Pulp/ 4: Heat Occisia/ 5: Blue Pulp)
