Observatory - table of costs and FP rewards

To change the range of levels or the value of the bonus from The Arc, use the form below.
Block indicates the number of Forge Points that an owner should invest at a given level of Great Building so that the investor paying the FP in the amount of the return plus the bonus from The Arc has guaranteed the place. On some levels, with the high The Arkc bonus, this value is negative, which means that the investor can guarantee the place for less than reward for this place.
