Valndrar Family Sword
Phantom’s Breath; + 4 Keen Medium Adamantine Longsword Of Frost
The longsword has the natural ability to bypass hardness when sundering weapons or attacking objects, ignoring hardness less then 20.
Upon command, the longsword is sheathed in icy cold. The frost does not harm the wielder. The effect remains until another command is given. A frost weapon deals an extra 1d6 points of frost damage on a successful hit.
A thundering longsword has double the threat range. This benefit doesn’t stack with any other effect that expands the threat range of a weapon (such as the keen edge spell or the Improved Critical feat).

Damage 1d8 + 4 + 1d6 frost (17 — 20×2)
