Q&A
A. Why isn’t there an xxx version?
Q. Eirin Yagokoro's Pharmacy is a simple meme mod casually created by the author in their spare time and is not actively maintained. Thus, only certain fun versions will be experimented with :)
A. Is there other features to be added in the future?
Q. According to official lore, Eirin Yagokoro has a few more potion-related spell cards like Butterfly Dream Pill - Nightmare, Butterfly Dream Pill, and Jade Rabbit Incense, and we'll look into filling them out.
Introduction
- Potion of Hourai
Yagokoro Eirin’s forbidden medicine, possessing the power to be undead. After consuming the Hourai Potion, the player will no longer die.
Yet, eternal life may well be a curse. Once the Hourai Potion is taken, impurity floods the body, and there is truly no turning back.
Crafting the Hourai potion requires adding Flesh to Ultramarine Potion during brewing.
- Potion of Ultramarine
Eirin Yagokoro's healing potion, which also removes defilements.
What is defilement? Simply put, they’re bad omens.
Beyond that, its Ultramarine effects also grant the player a "second chance"—by temporarily reducing maximum health, the player can avoid death.
Oh, and while Potion of Ultramarine has purifying properties, it absolutely cannot cleanse the endless corruption brought by the Hourai Potion.
Crafting Potion of Ultramarine requires adding a Golden Apple to an Awkward Potion during brewing.
- Potion of Unrivaled
"The master said this is only for emergencies... Huh? You drank three bottles?!"
An emergency medicine developed by Yagokoro Eirin for Reisen, granting the ability to rapidly boost attack and health for a short time.
Though effective, don’t get too greedy (lol).
Crafting Unrivaled Medicine requires adding Torchflower to an Awkward Potion during brewing.
- Flesh
A material for crafting the Hourai Potion, obtained by shooting oneself while tainted by impurity.
