Fully boosted is 30 boosts. So, (creation cost * 31) + 1,100 = total cost.
Why 31 and not 30? Because you have to pay to build the dot too.
And why the extra 1,100? Well, ya gotta pay for CEQ too, my friend!
So, for a dot in one of your Free Player Slots, the cost is just 1,100 for the CEQ, since the boosts are free.
100-cost dot totals up to 4,200.
200-cost dot totals up to 7,300.
300-cost dot totals up to 10,400.
Also, if you're not already a
PREMIUM member, I highly recommend it. ANY Flex purchase unlocks Premium status, so you can spend $2.50 to get 250 Flex AND an extra Free Player Slot. If an extra Free Player Slot isn't worth $2.50 to you, I don't know what is.
Hope that helps!
