The formula is rather simple btw.

1/(Mage Path +1 - Path Required) * listed fatigue + Enc Fatigue.


So if your mage is e4, with enc 3, casting an e4 spell

1/((4+1 -3) * 300 = 150 + 3 = 153 fatigue

If you cast Summon Earthpower...so you are now an e5:

1/((5+1) - 3) * 300 = 100 + 3 = 103 fatigue.
