Then,
@Kenainath, I cannot help you. Because by all indications, your ST is a railroading asshole who's got no sense of mechanical balance and who is rampaging all over the social contract like Isidoros.
Like, wow,
what the fuck, stopping you buying your own fucking Native Charms. No.
Fuck that.
You're an Infernal. Your native Essence 6 Charms should be competitive with any Essence 6 SMA, and also be easier to get (because Native), easier to learn (because Native), and not tied up in a Martial Arts tree (because not Martial Arts). If the ST has such a Martial Arts boner that he's banning you from buying your own fucking Native charms until you,
out of character, write him a whole new Charm tree and you're very uncomfortable with that...
... then that person needs an intervention. Fast.
