Chance contagieuse

Only enhancement from spending cosmic fragments with Herta (on the last stage right before the boss) counts as "actively enhancing" blessings.

Probably a reference to the Chinese version (which has the same name) of Up the Ante, a perk by Ace Visconti in Dead by Daylight. It increases the odds of every survivor succeeding a Self-Unhook attempt by a stackable 1/2/3% per Token (which is granted for every Survivor still in the game), up to a max of 3/6/9%.
