Unusual uses for spells?

Yeah, what the title said. I'm sure we've all used tricks in ways that the mod author probably didn't predict when he designed them, so let's share some of our more interesting uses.

As for me, a simple raycast smite spell works decently in combat, but where it truly shines is farming ender dragons for draconic evolution. A single smite blows up each crystal, even when they're encased in iron bars, and it would be even more useful if I didn't have (and need, since it's skyfactory) flight, since it'd hit from the ground.

Conjured blocks are also wonderfully versatile; I use them to clear out large chunks of water/lava, and with a timer, there's no real clean-up. Sure, sponges could do the same, but why on earth would anyone use vanilla items? Like, ever?

For those few times when I really, really want to gtfo of a situation, I keep a low power caster-focused explosion in my CAD and an eidos reversal in my chest. It's not hugely reliable, but it kept me alive a few times when I stepped off my platform in SF3.

So there're a few of my fun little tricks, and I'm far from the most creative here. What've you guys come up with?
