Question about Neurobiotic Boosters

[AckerZ]

Do Neurobiotic boosters increase your skill gain chance or do they increase the value of skills gained? Hard to tell with the 10% pills.

Im fairly sure its skill gain chance but just want to double check.

Can confirm ran some tests today while crafting, its 100% chance not value.
