I just expected the added bonus to be displayed somewhere easier to notice like the skill button that displays what skills are activated or something but since it's not, unless you read the wiki or was trying to figure out the math behind total power, you probably wouldn't have ever noticed. It's not even mentioned in the How to Play tab unless I missed it.
