Regular Swords – Regular run-of-the-mill weapons, good for quick attacks in rapid succession, but not great at dealing out heavy damage.
Sickle Swords – Quicker than Regular Swords, can also deal out some nice Bleeding damage along with their regular damage.
Dual Swords – Specialize in dealing out rapid attacks to any enemy, but don’t have very long reach, you’ll have to get up close and personal.
