ah, so casting the spell at such a low force is actually a good thing because it gives the spell at force 2 a threshold of 4 to be noticed, and also decreases the amount of time it takes for the spell to become permanent. I don't like casting spells at low force, though, because it reduces the amount of hits that count. With a force 2 spell only 2 hits count... not a big deal in this situation, though, unless those ganger grunts have some counterspelling up.
