You gain Infinity Dimension multiplier based on eternities (x^log4(2x)) 10 (This has a soft cap at 125,000 eternities.)


where A = # of Eternities (max 125,000)

and B = # of Eternities - 125,000

In other words:

Below 125,000 eternities: (A/300+1)log4(2*A+1)

Above 125,000 eternities: [(1253/3)log4(250001) ≈ 3.146e23] * (B/300+1)*log4(2B+1)

Unlike the IP Multipliers, you can buy EP multipliers without buying all 6 upgrades. It has a base cost of 500 EP and the price increases depending on the price of the upgrade. Once the price of the upgrade reaches a certain value, the price will be recalculated with the new price multiplier.
