Experience enhancing Book

"You are currently reading What Are Old Folk Good For Anyway?
Increases all EXP gain by 25% for 31 days
24 days, 04 hours, 18 minutes and 39 seconds"

I understand this book boosts lvl exp and not Crime exp. But does this book has any effect on Company exp gain if I'm the director ?

chode toh? tai na? xD

Wait, I thought it included Crime EXP?

also weapons experience, and crime xp. I'm probably forgetting something. Could be a good choice for dog tags or elimination. Pick a month when you'll be very attacky.

It only includes leveling experience. Company experience is directly linked to your total company income.
