From now on, assume that any use per day of an SLA or SNA beyond the first requires acquirement of SFP at twice the number of use per day:
1st use = 0 SFP
2nd use = 4 SFP
3rd use = 6 SFP
4th use = 8 SFP...and so on
Each 'use per day' increase obtained through leveling or by spending Roleplay Credits, will eliminate the SFP cost for that number of use per day. This means that if a character has an SLA or SNA they can use 3 times per day, they would ignore the SFP gained from the 1st through 3rd uses per day, but if they chose to acquire SFP in order to use it a fourth time, they would gain 8 SFP.
If a character has more than one SLA or SNA, they may use each up to the maximum number per day allowed even if these maximum levels are different without accruing SFP. They will begin accruing SFP as normal at the number of use for which that particular SLA or SNA reached its daily limit.
