Someone correct me if I am wrong but the sustaning foci is to "sustain" an already casted spell, and limits of force still apply as far as I see it. I cant see how someone can exploit it.
Without edge:
I cast a F1 detect Blah spell, I get 4 hits (on my 12 dice), my hits are capped to 1 due to it being a F1 spell and I hand it off to my Force 1 Detection Sustaining Focus.
The spell continues to operate at F1 with 1 hit, and I don't take sustaining penalties.
With edge:
I cast a F1 detect Blah spell, spend a point of edge for extra dice and get 7 hits (on my 18 dice), my hits are not capped because I spent edge and I hand it off to my Force 1 Detection Sustaining Focus.
The spell continues to operate at F1 with 7 hits, and I don't take sustaining penalties.
Now, with a lot of spells, this doesn't matter all that much because they have a minimum force unrelated to their hit cap or because their force figures into their functioning in some meaningful way above and beyond the hit cap. But for a subset of spells, the only thing force really changes is how easy it is to dispell the spell and the hit cap, the actual active effect of the spell is entirely dependent on hits.
Some people some to think this is weaselly, I just think it's a good reason for F1 sustaining foci to exist, as otherwise they are pretty much useless (most sustained spells need net hits above a threshold to actually DO anything, and the base threshold is 1). Edge is a limited resource, and the spells are absurdly fragile.
