Here are two variants I use, both submitted to the Fan Grimoire. The second is exactly what you ended up with. The first is really useful at other times, and can probably be used with a Familiar bond, though I'd have to double-check how far you are from the bond connected to you (not how far from your Familiar). I like to Master these, which can be done by Mastering one of them with Adaptive Casting; that way you can do things when silenced, bound, etc.
