Transforming Mythic Europe.
Where in TME can I find this?
Page 40, under Living Conditions. It doesn't mention the Augustans - that was me converting 40 levels of hermetic effects to EF scale ((Magnitude+4)x3)
Isn't EF scale more akin to 3 per Magnitude?
Usually, but looking at the base guidelines for Virgilian magic and comparing them to the Hermetic equivalents that doesn't seem to be the case in this instance - though I suppose I can see an SG accepting either of those.
Remember though, due to the scaling, Augustans have a (relatively) easier time with large rituals than smaller ones so it probably wouldn't make much difference in the long run...
