Wut? SC dies for no reason...

The mage targeting algorithm is pretty decent and it'll generally go after high-HP targets with single target/small ae spells, like it should.

SoL is also range-limited at 35+, so the majority of the casts may have ended up in your frontal chaff with a few casts from powerful or more forward-placed mages aimed at the big guy.
