Not unless I'm missing something. it says you can skip the ASF chance for [cold] spells while wearing it, though.
Eh, PhaedrusXY brought it up. Skipping the ASF is meaningless if all of my spells aren't cold anyway.
Anyways, here is my argument:
Eschew Materials says: "You can cast any spell that has a material component costing 1gp or less without needing that component."
Snowcasting says: "If you add a handful of snow or ice as an additional material component to a spell when you cast it..."
Therefore snow is an additional component of the spell, and not just an extra thing I need to cast it in general, as it gets added to the list of material components necessary to cast the spell if I'm using the feat. I interpret the third paragraph as more of a way to prevent players from lugging around a whole bunch of snow in a bag of holding and abusing the feat. If the extra material component is eschewed the third paragraph becomes non-applicable.
I've seen it go both ways Bowen. You just want my group to lose.
