Starsoul Flask I

A special antidote used to ease Illusory Plague, outwardly no different from an ordinary glass bottle.
Inside are seven or eight flickering lights—neither dazzling nor holy-looking. Just a faint shimmer, like invisible fireflies.

Since Starsoul Flasks are currently the only way to fight Illusory Plague, they're extremely precious on the highlands. Production is extremely limited, so even money can't buy one among common folk. The Creed distributes Starsoul Flasks to the public on a regular basis to ease Illusory Plague.

The making of Starsoul Flasks depends entirely on High Priest Lothar, the only person on the highlands who can purify Illusory Bloom Crystals.
