Ever wondered how much actual boost you are getting when you have several boosters active??
Right now I have several 20%, 30% and 50% RP boosters active from the “Travel Suitcase” event - you get dozens of these if you buy a lot of these cases.
Just mouse over 1 of the boosters in your Items inventory - here’s what the total effect looks like for me right now: (works the same for SL boosters too)
