Player 9:
Why is it that most of my ideas for characters end up with needing a lot of XP in non hermetic skills?
Let's play a Verditius.
Sure, just remember to add a decent craft skill and sink som XP in Philosophiae.
Hey, those Ramius Flambeau look interesting.
Oh they are, and in addition to those weapons skills you probably need a bit more strength.
I guess I just want to complicate it for myself.
Sure, a Verditius and a Ramius Flambeau, amongst others, can be Ability intensive, but it's not a bad thing. My Criamon has Animal Ken and Handle Animal that he'll be investing it, and probably a few more, like Bargain.
If it's part of the character concept, go for it. Plus, it might give your Magus something else to do and use even in avergae-high Faerie/Infernal/Divine Aura. And when you don't want to advertise you're a Magus.
You might not have a score of 5 in either of the Abilities. But remember that your apprenticeship has cut into your time investing in them, but has given you tools that will build upon them, and you can increase them in time.
