Key composition
A key has three characteristics, which together determine what a key is. These three characteristics are rarity (common, rare, rare, super rare), shape (ore, feathers, gears, stars), and attributes (fire, ice, thunder, wind). The rarity is determined by the Pure Key or Void Key used when making the key.
Void Key and Purity Key
These two types of keys can be divided into four situations:
Void Key: No improvement in rarity;
Pure Key (no effect four): rarity increased by 1 level;
Pure Key (Effect 4: Rarity UP): Rarity increases by 2 levels;
Pure Key (Effect 4: Rarity UP·2): Rareness increased by 3 levels.
The improvement of the rarity level refers to: when using the void key to make a key, if the key is a common level key, the pure key (no effect four) can be used to make a rare level key, and the pure key (rarity UP) can be used to make a rare level key. It can be made into a rare level key. Use a pure key (rarity UP·2) to make a super rare level key.
For situations where the Void Key can be used to make common (probability: n%)/rare (probability: (100-n)%) keys (this situation mainly occurs when making keys for monsters), use the pure key (No effect four) can be made into rare (probability: n%)/rare (probability: (100-n)%) keys, and so on.
When some bosses are made using void keys, they can be made into rare-level keys. This situation is similar to the common/rare examples above, and the analogy will work.
