Multispell can be pretty sick. Especially if you're an Ultimate Magus sing Augmented Spellcasting and can start off with a Quickened Time Stop, because after the Time Stop expires, you can cast 2 more spells, or more if you've taken Multispell multiple times. Think of following up your Quickened Time Stop with Quickened Disintegrate and then an Intensified Meteor Swarm.
