The Fever Crank was first seen in 6.0.0, as part of the "Re:Merge" event. It is a limited time crank that offers unit parts.
Overview[]
A Fever Crank is a combination of both the Box and Step Up Cranks. The first pull is free, while further pulls cost 1,700 medals each and are rolled in batches of ten, like the Box Crank. The pool consists of three potential rewards of the featured unit, a Super Rare and a Rare section.
Normal genies will appear whenever the player pulls a 30x parts of random Super Rare unit or 10 or 5x parts of the hot unit. Golden genies appear if the player rolls the 80x of the hot unit instead. The 80x reward has double the rate of the 10x and 5x rewards.
Fever Crank units are usually intended for a specific faction to boost their strength. It is recommended to attempt a fever crank after amassing at least 35,000 medals due to the crank's extreme volatility.
Fever System[]
When the player pulls Rare unit parts from the Fever Crank, the player is given 1 Fever Point. If the player ends up pulling only Rare units from a single play, then a 2x multiplier activates, causing every Rare unit part acquired to give 2 Fever Points instead of one, which can effectively halve costs if pulled early.
When the player hits 200 Fever Points, they are automatically converted into 80 parts of the featured unit, allowing the player to obtain the unit if they haven't done so already. In returning Fever Cranks that feature multiple hot units, the player can select the unit they want.
