Can someone please explain to me why this has the water descriptor and is cast by druids? Edit
Seriously... I've read the description, and nothing about it suggests that it's a water spell. It's swords, not water, raining down from the sky.
Also, I kinda wonder why it's supposed to be available to druids. Something that makes a lot of worked metal fall from the sky sounds like it'd be a pretty big violation of the druidic oaths. Aren't they supposed to avoid using worked metal? I get that druids are supposed to be the most offensively potent of the divine spellcasters among the 11 core classes, but their spells are supposed to have an overall "nature" theme.
