The Moon Blade's stats after being imported into The Witcher 2

The Moonblade is a silver sword of elven design. This deadly silver sword is given to Geralt by the Royal huntsman in Chapter V as a possible reward (the other possible reward being G'valchir) for bringing in all ten trophy monster heads. Merely killing the monsters is not sufficient, their heads must be returned for the quests to count. It is used against monsters and has little effect on humans.

Described by the Royal huntsman as "splendid", and it is. Can neither be bought nor sold.

It is the best silver sword in the game, the best steel sword being G'valchir.
