Divine Retribution: took a long time to adjust
So, I reworked the formula into this:
neophyte F(5+2sp)
basic F(10+2sp)
strong F(15+2sp)
skilled F(20+2sp)
there's also another option:
neophyte F(1+1sp)
basic F(2+2sp)
strong F(3+3sp)
skilled F(4+4sp)
What is this formula based on? What were your guiding principles?
