Viper Venomous Steel Sword

The Viper Venomous Steel Sword is the high-level steel blade of the Viper School gear from the Hearts of Stone expansion. It combines +25% Aard Sign intensity, +75% critical hit damage and a 15% chance to poison.

The diagram can only be picked up during Open Sesame!, inside the Borsodi vault, so it is easy to miss for good. It is a big upgrade on the early Viper Steel Sword, and its partner is the Viper Venomous Silver Sword.

The matching armor arrived in the same expansion: Viper Armor, gauntlets, trousers and boots.
