[svn] Give Frostdusk a effect like other magic capstones?

[SageAcrin]

(Wildfire, Crystalline Focus, etc., which recently got neat secondary unique effects in SVN.)

I was thinking that a small chance for cold damage to blind and for darkness damage to freeze might be really neat, or something along those lines, since it has effects on two elements.

Or maybe it could just convert cold damage partially to Darkness, since that'd be a simple, and mostly beneficial given its nature, effect.
