Antarctic Blade (3.5e Maneuver)

''Visible cold winds whip around the blade of your weapon as it seems to transform into a razor-edged icicle. Snow pours off of it, blown on the winds, and anything it strikes turns to ice.''

For the rest of your turn, all of your melee attacks inflict 3d6 + initiator level bonus cold damage. Additionally, any critical hits you make cause your target to be slowed, as the spell, for one round less than your weapon's critical damage multiplier.

This maneuver is a supernatural ability.
