That's only 8 parts, though. A witchwood altar(3 parts), or nether quartz/nether brick if you wanna be weird, plus half decent caps(so Lapis blocks at least, which give +5 parts), can make this.You need a relatively high level crafting altar for this one, but it's really fun in multiplayer.

I call it hit 'n' run. Hit your "friend" when they're holding something valuable, and proceed to jump 400 meters into the sunset after stealing it.
Good spell for PvP, though. I thought kinda thought Leap was a bit like Fling, but I'm likely wrong as usual.
