4th Edition Nyss from IK

[Ceiling009]

I really love the IK setting, and more so their obligatory Elves. So I decided to try to port over my favorite Elf to 4E. Even though they're elves, I'm not treating them as such, so they can't take any of the Elf Racials, just like Eladrin or Drow.

What do you guys think? For those familiar with the Setting, do you think it works with the spirit or at least looks like a good port? And for those who aren't familiar with the setting, what do you think over all?

Edit: the claymore and feats slightly changed.
Edit 2: Changed out Winter's Edge, I think it works better like, sort like a smite... also changed out the feats, and gave the a level scaling Cold Resistance, these guys aren't called Winter Elves for nothing.

[Azerian Kelimon]

The Claymore's b0rked. It shouldn't be a light blade, full stop.

Also, change the power to have a base independent of W, because some classes don't use weapons.

[Ceiling009]

Actually, all do; and the only time they won't be is when they're using implements; but then again, why bother using it? I could probably go with giving that effect as a encounter power to any attack. The Claymore is slightly... out of line, but I'm changing it to a little bit.

[Azerian Kelimon]

Even then, change it. A wizard has NO use for weapons whatsoever, he DOESN'T have them. Give it 1d6 per tier.

Now that you need two feats the claymore is more balanced. It's still too powerful, but it's better now. Maybe give it a proficiency bonus of 0 and a penalty for being nonproficient, and it should be balanced.

[Ceiling009]

No... I think penalties from non-proficiency is going against something inherent in 4e... It's a damn good weapon for sure, I might lower it to 1d12 instead of 2d6.
But the thing about the power is that it's tied to a weapon, cause you seriously are never unarmed, as even an unarmed strike still works, a wizard could feasibly punch someone you know... But I'll contemplate it.

How about if I change it to...
Winter's Edge
Encounter ✦ Cold
Minor Action
Effect: One your next attack, if you hit, you deal additional cold damage equal to Dexterity modifier. If you miss, you still deal cold damage equal to your Dexterity modifier.
