Just got my fifth copy of the 4* student council CE. Does it stack? Or is it just gonna be 20% even with 5 of them?
MLB Student Council gives 50% to the spawn rate.
Also, if you’re running 5, it’ll stack to 100%.
I’d say, a sixth copy should be an MLB. You can MLB with 5 too - but only if you can easily find friends who also have an MLB Student Council.
Otherwise you lose out on 100% spawn bonus, and 100% spawn bonus is some nice stuff.
