Items/Compounds

Compounds are items that are typically created through a skill called "Compounding" and can be created manually or through the use of a Legendary Weapon. Although many compounds can be made through the use of a Legendary Weapon, all products of the Legendary Weapon will be normal quality despite the input ingredients. (Using any low, mid, or high-quality ingredient will result in normal quality products). Some naturally occurring plants share the same use or effect as certain compounds so they can sometimes be used as a substitute and are therefore included here as well.

Normal Medicine
Normal Medicine is a medicine that treats certain illnesses. Depending on how it is compounded, it can be drunk to treat illnesses or used topically to help treat wounds.

Nutritional Supplement
Nutritional Supplement is a medicine that relieves fatigue. It is also effective as a method of rapidly recovering from malnourishment and is responsible for unlocking the Calorie Shield, Energy Shield, and Potential Energy Shield.

Antidote
Antidote is used to cure poisoning effects and is responsible for unlocking the Anti Poison Shield.

Weed Killer
Weed Killer (or Herbicide) is typically used to kill weeds but can kill a large variety of plants and it happens to work pretty well against plant-based monsters as well. It is responsible for unlocking the Glyphosate Shield.

Gunpowder
Gunpowder is used to create explosions when set ablaze. By collecting it in bags and setting the bags on fire at the appropriate time, it is possible to create makeshift bombs however when Naofumi attempts to use them against an enemy the power of the bombs are degraded. They simply burn the bag to ash due to either his lack of attack stat or the shield's restriction on using weapons besides itself. It is responsible for unlocking the Plant Fire Shield.

Acid Water
Strong acid is stored in a glass bottle and seems to be a little less acidic than sulfuric acid. It is used during inside the Spirit Tortoise on the Mimic Type Familiars that were imitating the floors and walls blocking further exploration to reveal their locations.

Magic Power water
Magic Power water restores magical power when drunk, however this medicine requires the user to imbue magic into the mixture to activate. Therefore, it may be difficult for some to create this medicine.

Holy Water
This water is able to treat curses to allow them to heal. It is mostly available at the church. The cost ranges from low/poor to good quality and charged a price accordingly.

Soul Healing Medicine
Soul Healing Medicine restores SP, the power to use the skills from Legendary Weapons and Vassal Weapons. This medicine is expensive to both buy or create. For non-heroes, this drink apparently tastes good and improves magic and concentration. The monsters at Cal Mira Archipelago often drop materials for soul-healing water.

This medicine has a unique effect when consumed by Spirit People of Glass' World. This race does not have levels or magic power, but instead of single power source called energy. This energy level determines the Spirit's power and naturally increases relatively slowly. Most magic and medicines are unable to affect this energy level, but Soul Healing Water drastically increases which - making it incredibly valuable to Spirits. The people of Glass' World did not know of Soul Healing Water until Naofumi brought it over from his world.

Insecticide
Insecticide is made by mixing and dissolving grass that repels insects until it hardens. It is used to kill insects and is also pretty effective against insect-based monsters. It is responsible for unlocking the Killer Insect Shield.

Lukol pill
The Lukol pill is an herbal supplement that aids in the recovery of SP, MP, and status magic. During the fight with the Spirit Tortoise, Filo received it from the Queen to give to Naofumi to allow him to continue the fight. It can likely be made by compounding. This may be related to Rucolu fruit which is used to make alcohol. Apparently Rucolu fruit refills magic power and SP when it is used but only Naofumi is able to handle it due to his alcohol nullification.

Elixir of Yggdrasil
The Elixir of Yggdrasil, also called the Medicine of Miracles, is capable of curing most illnesses and boosting energy. Simplifying the compound, it's sap from a Sacred Tree. The medicine required ointment, magic water, soul healing water, and a few others ingredients to be mixed together into a supernatant fluid with the toxic parts being filtered by exquisite distribution. The medicine could only be made once at the time due to the ingredients it costs and the risk of failure. Although the Spirit Tortoise Sacred Tree Shield assists in the creation of the medicine, it is so difficult to make that Naofumi could barely make one, even with the help of his shield. It is first referred to after the Zombie Dragon incident when it was used on the Old Lady that assisted in defending the village from the wave. The first time Naofumi created it he used it on Atla to cure her hereditary illness. It is an extremely valuable medicine. While this medicine is incredibly powerful, it is not all-curing. If someone receives a grave enough injury, they can die despite this elixir or any magic used.
