Embrittle Bones (3.5e Maneuver)

''Everything gets more brittle in extreme cold, even your enemies. The trick is to bring the right cold''

As part of this maneuver, make a melee attack. If it hits, the target takes normal melee damage, and then takes double physical damage from every source that hits them, to a maximum of +3 damage per attack. If the target takes cold damage, the duration of this effect is refreshed (three rounds after the last application of cold damage), and, if the target fails a saving throw against the effect (or against DC 15 + your Constitution modifier if the effect doesn't allow a save), they are also fatigued.

This maneuver is a supernatural ability.
