In-game description
"A derivative of the long sword, the two-handed sword is significantly longer, both in blade and hilt. Its primary function is cleaving mounted knights and breaking up pike formations. This magical version is even more capable of such functions, serving as a fearful reminder of what comes of the union between weapons and sorcery."
