Precocious Pressure 20 proof
Precocious unlocks after beating the game on the highest Pressure. Its rule is demanding: the first level-up is a Branching Evolution, but the first boss does not drop a Boss Fruit.
A public August 16 screenshot batch now gives a clean completion benchmark: Pressure 20 cleared at level 54 in 21:43 with 7,936 damage, 2,281 damage taken, 54 kills, 73 mutagen, and 23 POIs.
Adjacent screenshots from the same author and timestamp show Precocious at 20/20 and the Pilferer's Tail cosmetic unlock. The named evolution route is not printed, so it remains Unknown rather than reconstructed from icons.
