I really like the new Ice Shards. It's a D6 now, and it's much harder to pull off that... 7d4, well it's with a 18 wis, and 4 ranks, taking a 10, it's 18 total, making a 4d6 line of piercing cold. Thats pretty decent, but not terribly... well horrible sounding. It doesn't sound like a insta-kill for a lot of the non-con based classes and monsters, while it gives a hefty reason not to mess with a waterbender.
