Similar Spells

@Christian_Andersen

I know my own Troupe feels that PoF and BoAF are similar spells, and I am (potentially) abusing that fact for Magic Resistance Mastery.
Initially I would not have felt that way, but what the hey.
They both have the same basic effect (create fire), and both have the same RDT, however their effect is at different intensities hence different guidelines.

PoF and BoAF are a text-book example of similar spells. You can't get a much clearer example than that.
They have the same RDT and closely related effects. "Closely related effects include such things as doing damage with Creo Ignem" (ArM5 p101)
