Potions

Potions are designed to instantly restore resources that would otherwise take time to replenish, such as stamina. They are only dropped from loot boxes and have about a 10% chance of being found, meaning that on average, one out of every ten loot box items is a potion.

In Questfall v.1, only one type of potion is introduced - the Stamina Potion. However, new potion types will be implemented in future versions. For example, Mana Potions.

Potions do not have levels, but they can be one of six rarity tiers, gaining power with each tier. Therefore, potions of the same type and rarity are identical and have exactly the same properties, such as effect, weight, evolution cost, etc.

Like any other RPG item, potions can be scrapped for Essence or sold on the marketplace for Gold (F,E,D) or QFT (C,B,A). Users can also evolve the rarity of potions by merging identical bottles, the number of which depends on the type of potion.

For example, Stamina Potions assume that two potions are merged to evolve. Therefore, two F-rarity potions will create an E-rarity potion, two E-rarity potions will create a D-rarity potion, and so on.

Stamina Potion

When consumed, a Stamina Potion will restore a percentage of the user's Stamina Reserve, depending on the rarity of the potion. The Stamina Potion of rarity F restores 10% of the total size of the Stamina Reserve, and each subsequent rarity tier doubles the effect.

Since evolving requires two potions that have the same resultant effect, it might seem that there is no point in evolving. However, the weight increases more slowly, so an E potion, for example, has the same effect as two F potions, but takes up less inventory space.

Rarity	Effect	Weight	Drop Rate	Scrapping	Evolving
F	+10%	100g	$\frac{32}{630}$	+11es	-
E	+20%	174g	$\frac{16}{630}$	+14es	2xF+10es
D	+40%	241g	$\frac{8}{630}$	+19es	2xE+30es
C	+80%	303g	$\frac{4}{630}$	+26es	2xD+60es
B	+160%	362g	$\frac{2}{630}$	+35es	2xC+100es
A	+320%	419g	$\frac{1}{630}$	+46es	2xB+150es

Scrapping and evolving values in the table are calculated for a Crafting attribute of 0, where 11es means 11 Essence. Drop rate assumes no other type of potion is present. Weight is calculated based on: $Density=Rarity^{-2.2}$.

The potion adds the full amount provided by the effect to the reserve, which can hold more than its nominal size. For example, if a user has a reserve size of 10,000 and only has 4,000 stamina left, a C-rarity potion will add 8,000 (80%). This will result in 12,000 stamina in the reserve.

However, to prevent automation by gaining a huge amount of stamina before running a bot, a potion cannot be consumed in advance if the reserve is full.
