Oh we haven't talked more about the spirit binding stuff. I'm thinking she could summon a F4 Beast spirit with the concealment power, as a back up for security every evening. If she eventually gets one with 3 or 4 services owned, she will try to bind it overnight and not use up a service on him just yet if she's successful, though she could summon something else by that point.
That will leave enough reagents for another binding if it makes sense to attempt one during a run, and a beast spirit will be a good trump card in sticky situations, with its superior physical abilities and capacity to assist with combat spells.
Ok, so, first we summon:
12d6.hits(5)=8 - reduced to 4 hits by limit
Spirit resists
4d6.hits(5)=0Ok - that is about as good as you are going to get, and on the first roll too!
You resist drain of 2DV
13d6.hits(5)=2So no Drain.
Next up is the Binding Test: Binding+Magic
12d6.hits(5)=3Spirit Resists (Forcex2)
8d6.hits(5)=4
That sucks - you rolled below average AND he rolled above. The opposite of the summoning test

Amy resists Drain (8DV)
13d6.hits(5)=5So, 4 hours, 100 reagents, and 3 boxes of Stun later, the spirit is still there, but is not bound. After an hour of rest or so, the Stun damage goes away.
As an aside, it doesn't actually say how you determine if the Drain is Physical or Stun, I imagine it is the same as Banishing, i.e. if the Force of the Spirit is greater than your Magic it is Physical, otherwise it is Stun, but I'm not sure.
Also, not that it mattered here, since you only rolled 3 hits on the Binding test, but the limit on that binding test is the force of the spirit, it is probably worth spending reagents to raise the limit if you try it again. I thought of it after I rolled, and had I rolled more than 4 hits I would have stopped before I rolled drain and asked you if you wanted to use reagents, but with only 3 hits it is a moot point.
