Some help with summoning and binding thamaturgy

[Archmage_Cowl]

Okay so i have a cool idea for a wizard with water magic to create like a guardian knight out of water and i figured this would be best represented by summoning and binding some type of powerful water spirit. So my question is can someone tell me if i have the base idea of how this should work.

First you would create the circle barrier which works like a reverse ward to beat their conviction so at least 10 base(for a conviction of superb(+5)) plus another 3 or 4 for duration.

Second you would summon the entity which is an attack against their conviction so again assuming a superb conviction this would be a difficulty of 10.

Third would be the binding which would again assuming superb conviction would take 4 for their stress track +4 for their two mild consequences, +4 for their moderate, +6 for their severe, +8 for their extreme, and maybe a +1 to take them out? which would come to a total of 26 or 27 depending on which is nessacary. Then going with the 26 version you would put it's extreme consequence as some sort of aspect relating toward its binding to you? and then you can compel that aspect whenever you need it to do something?

I think thats how it's supposed to work. If it is sorry for wasting your time but i would really like to be sure i'm doing it right. After all as bob says its better to get the containment and fail the summoning than get the summoning and fail the containment. lol
P.S. If anyone has any critique or advice or comments please speak them.

I believe your math is correct. However, you might need a longer duration for your containment spell. If you have Superb conviction you'll be putting about 5 shifts of power per exchange into the binding spell. That would be 5 to 6 exchanges to build up your 26 - 27 shifts.

Thanks!
on a side note i thought when you put more shifts into a ward or thamaturgy spell for that matter to extend duration you got the next part on the time table and i think the base for a ward is till sundown(an afternoon) so 3 more shifts into duration would increase it into a week. at least thats what i got. It doesnt matter much either way just the order in which i have to do things lol.

Also i had an idea that after binding such an entity it would be cool to have it as like a tattoo or an item or something you could carry around until you needed it to help out so i was wondering would that be like a thamaturgy transformation maneuver with a duration of however long i wanted before i would need to renew it?

on a side note...

I think you may be right. I flunked Thaumaturgy!

Also i had an idea that after binding such an entity...

Sounds like a companion a la SotC.
