Potion

Potions are fluid items which are designed to replenish a variety of stats, and therefore have varying effects. They are generally used by drinking; however, health potions can also be applied topically, being sprayed or poured onto wounds.

Appearance
Potions resemble drugstore-variety restorative drinks and remedies. Different types of potion are different in color, but otherwise look identical. Health potions, for example, are red.

Potions come in small 100 mL bottles, shaped like rounded cubes; the bottles are translucent with opaque white lids. These bottles are made from dungeon materials so that they can be placed in the inventory. Since it is difficult to create such bottles on a massive scale, due to the high price of dungeon byproducts, potion bottles can be taken to the Hunter Association and recycled in exchange for points that can be used in the Hunter Mall. Low-rank Hunters often make use of this in order to buy equipment. Mid- and high-rank Hunters, on the other hand, recycled at low rates, and had to be targeted by a recycling campaign.

Effects
Potions are designed to heal and replenish the stats of an Awakened person, though they can likely be used on Unawakened people as well. Each type of potion has its own effect and its own strength.

Types
Potions are graded and separated by the stat they target.

Mana potions
Mana potions replenish one's mana reserves. They come in apple and orange flavors, as well as more special flavors like Swiss chocolate. Mana potions are factory-made, created from finely-ground magic stones.

Health potions
Health potions (or vitality potions) replenish one's vitality; in other words, they heal. They are 10 times as expensive as mana potions of the same grade, due to the complexity of their creation. Health potions are handmade by healers, and affixing healing effects to liquids is difficult enough that they can only make up to mid-grade potions. High-grade health potions and elixirs can only be obtained through dungeon rewards.

Low-grade health potions are not very effective unless they are sprayed directly on an external wound, in which case they can stop bleeding and sterilize the wound.

Elixirs
Elixirs appear to be extremely effective versions of health potions, presumably healing people significantly more than even the highest-grade health potion. They are incredibly precious and rare, appearing only periodically even in S-rank dungeons.

Stamina potions
Stamina potions replenish one's Stamina.

Granting potions
Granting potions were given to Han Yoojin as a reward for killing Rauchitas and obtaining the Legendary-ranked title Dragon Slayer. It is currently unknown what effect they have, as they are the only instance of such a potion, and were lost where Han Yoojin regressed.

Grades
Potions have different grades, according to their strength. High-grade potions affect their target stat with high efficiency, and heal or replenish a significant amount. Low-grade potions, however, have weaker effects.

History
4 years after dungeons appeared, stamina potions were created. They used the root berries of a tree that grew in a Japanese dungeon that appeared that year; their effect was discovered when Hunter teams noticed monsters eating its berries.

Original timeline, pre-regression
After being attacked by the Rauchitas, Han Yoohyun notes that he has a few small potions (presumably health potions), but that they won't be strong enough to heal his fatal wounds. Later, when Han Yoojin kills the Rauchitas in revenge, he earns 5 granting potions as a reward for obtaining the title Dragon Slayer.

New timeline, post-regression
Han Yoojin buys a set of 20 mana potions and another set of health potions at the Hunter Mall.

Later, after visiting Bak Yerim's uncle with her, Han Yoojin drinks an apple-flavored mana potion to replenish the mana consumed by using Promising Sprout. He also explains how potions work to Yerim.
