Infinite gold exploit with proposed sanctum change

With the two major boons granting "Picking up Aureus coins recovers Resolve" and "Gain 20 Aureus coins when you lose Resolve from a Hit" you can afk farm infinite gold in sanctum. This will be a problem with the proposed change "Added the Gilded Font to the end of each Sanctum floor. This allows players to convert 50% of their current Aureus to gold".

It is the same type of calculation as the aureus coins converted to experience/tainted currency/relics. It's logarithmic function which prevents such abuses.
