Actually Overwhelming Sceptre Blast's range is (Ess x 10) so it'd be 30 for her. And I can't figure out where you're getting your soak values, but that actually reinforces your point about how weak the early charms are.
For Pretty Soldier Declamation, why not change it so the damage dice work on every opponent who was a valid target for a Presence attack at the time of the Charm use? So you could do it at the start of a scene at a small group of enemies, but not a whole army.
For the soak, I don't see any harm in throwing a soak-buffing upgrade into the Form Charm.
Aside from that, I'm not sure I want to increase the power of the charms. I'd really like to be able to move this back down to a TMA, it's just that the charms after Overwhelming Sceptre Blast are too good for TMA.
