Would like some help making a gun mage

[Tedronai]

Not as much as you'd think.  I mean anyone can counter it with a hastily drawn and invoked circle in one exchange.  Even Plain Mortals if they've been taught how.  That's why I don't have as much problem as some with DoT spells.

Orbius cast at anyone with knowledge of circles is going to cost like an eight shift spell, be resisted like a three shift spell, and can be neutralized with no stress being taken the very next exchange.  It's only really good for mooks and beings that can't make a circle for whatever reason.

The above depends rather heavily on how you choose to represent circles mechanically.

True, it is a pretty vague area.

I'm not even sure if that works thematically. Once the Orbius-thing is on your face, I'm not sure that anything needs to cross from the caster to you.

Also, being able to spend your action to force someone else to spend their action means you more or less automatically win when you outnumber your opponents.

A valiant attempt to nerf Orbius, but probably not a successful one.

Pretty sure it does.  As described as a Spirit evocation, it sounds like it's either NN matter or a force effect that's essentially the same thing rather than something yoinked out of the environment.  Summoned NN matter goes poof when caught in a circle other than one it was summoned into.
