Album (Kingdom)

Albums are a class of item in Kemono Friends Kingdom which are equipped by Friends for the stat boosts and special passive effects they grant. The game uses two terms in reference to these items: Album and Set. An Album is any one of three individual left-side, center, or right-side pieces- labelled as I, II and III respectively- which are combined to form a Set. Albums will always grant a stat boost when equipped, but the special passive effects listed on each Album only activate when a full Set is in use.

Albums are sorted into four ascending rarities: C, B, A, and S. Albums of higher rarities grant larger stat boosts and possess more powerful passive effects when used in a Set.

Players can acquire Albums through story progression rewards, special events, and the Subway, and they can be levelled up using a family of items called Manuscripts, which are acquired in the same ways plus such means as the Redeem shop and Park.

Sets
There are 27 unique types of Set in the game, and each Set grants a specific passive or activated effect- called a Set effect- to any Friend who equips it. If a Friend mixes and matches Albums from different Sets, none of those Albums' listed Set effects will be active; a full Set must be equipped to benefit from a Set effect.

Attributes
Each individual Album possesses one of ten Attributes, each of which grants a different set of boosts- called an Attribute Bonus- to the base stats of any Friend who equips an Album with that Attribute. Albums do not need to form a Set in order for a Friend to benefit from each Attribute's stat boost, and the Attribute types of each Album do not need to match for their Attribute Bonuses to apply. The boosts granted by an Attribute increase relative to the rarity of the Album in question.

Albums of rarity C or B cannot possess the Sharp, Poisonous, Scaly, Slimy, or Hibernation Attributes; these five are restricted to Albums of A or S rarity.

Album Levelling and Enhancement
Through regular gameplay, the player will collect Manuscripts- loose pages detailing scientific findings in experiments done with Sandstar, performed and logged by an unknown author. These Manuscripts can be consumed to increase the level of any Album. All Albums start at level 1 and cap out at level 80. Levelling up an Album increases the values of its Attribute Bonuses, and can boost the power of a Set Bonus when all three Albums equipped are of the same level; if a Friend equips a Set with Albums of differing levels, the lowest-level Album's Set Bonus effects will be the ones applied to the Friend.

At certain intervals of an Album's progression, one extra copy of the same Album- the level does not need to match- must be consumed instead of Manuscripts in order for the Album in question to reach its next level. This is referred to as Album enhancement, and it both increases the Album's level by one and further boosts the potency of its Set Bonus; S-rarity Albums can even acquire a secondary Set Bonus effect at level 36.

Attribute Bonuses by Album Level
As mentioned, the stat boosts granted by an Attribute Bonus varies by both the Album's rarity and its enhancement level. The Attribute Bonus values of +1 and +80 Albums for which data has been collected are as follows; note again that some Attributes only appear on Albums of A or S rarity.
