Players are each allotted an initial pool of FungiBills (default 100), which they may use to buy Powers.
One-shot powers cost their level value in FungiBills, so a 1-point one-shot power costs 1 Fungibill, and a 5-point one-shot power costs 5 FungiBills.
A permanent power costs 2L points to buy (where L is the power's level), so a 1-point permanent power costs 21 or 2 FungiBills to buy, but a 5-point permanent power costs 25 or 32 FungiBills.
