Re: The Canteen (OOC)
Yea, with Mage Armor not being a spell and able to be activated reflexively without a roll, there's no need for the old 1e "cast it every morning with a day-long duration" ritual anymore, since you can just activate it for the scene the moment you sense trouble.
It is still detectable through Mage Sight, though, and I'd imagine in a situation like this it'd be seen as weird to have Armor up. Though any other spells I'm sure are fair game, it's not weird for a Mage to have a spell or two hanging on their person. Though what Stele said is definitely true as well.
Bast has no active spells up at the moment, she just has her Familiar with her, which would only ping your senses if you have Spirit 2.
