Re: The Canteen (OOC)
Congrats on the time off! I looked into the summoning and have two potential options for you:
A) You can cast Summon Spirit to entice the nearest spirit of Resonance: Electricity to come to you. Specifiying the target's Rank is not an option unless you personally know a rank three Electricity spirit that you can target individually, but just in case I built for that power level. You can use an advanced command to say "remain by my side until dawn" though this will require you to create the Open condition for them if you want them to manifest. Breakdown: +2 Reach for complex command, +1 reach Advanced Duration, +1 Reach for Casting Time, -6 Factors for Potency. Ends with a Potency 4 spell that technically lasts for up to a week/month (don't know your spirit level).
B) Same idea but instead you summon the spirit and command it with a second spell. This saves on having to Reach so high. The command spell allows you to give orders such as 'stay with me' at no additional cost so it is much easier to manage Reach-wise. For this one I have assumed you have a Spirit of 3, if not you will need more potency on the Command. Breakdown: Summon Spirit (1 Reach Casting Time, -6 Factor for Potency 4), Command Spirit (1 Reach for Casting Time, 1 Reach for Advanced Duration, 1 Reach for Sensory Range, -2 Factor for Duration, -2 Factor for Potency)
I will point out though that both of these require you to bind the spirit in question and are thus Wisdom sins. Atop that they do not prevent the spirit in question from acting of it's own volition while with you.
