She'll give some input on what you've got so far on your CS Draco.

For the weapon section, human characters never actually use magic on their own. Its always their persona doing the casting. 

The P4 version of summoning a persona is only possible because the TV world is a shadow world and thus more directly connected to peoples subconscious making it possible to summon a persona without need of an evoker. The only time we've seen a persona user not need an evoke to summon a persona was Takaya in P3, but he was an experiment and suffered for even being able to use a persona. 

Personally she'd prefer if people dont just copy the summoning process from p3 or p4 for the sake of creativity. Thats just her two cents, though
