The old "time stop + DBF" also still works. But if we're talking about 9th level spells, the game is kind of already broken. (Although meteor swarm can only hit a single target once now, even if it is caught in all four 40d6, 40' radius blasts.)
Hmm. I'm not sure it does, actually.
"This spell ends if one of the actions you use during this period, or any effects that you create during this period, affects a creature other than you..."
I think that could be read in a couple different ways, where DBF is concerned.
