"The Morning Star is long reaching mace weapon that deals a bit less damage and has a moderate rate of attack."
The length of The Morning Star increases it reach in comparison to a traditional mace, but also decreases its speed. This makes The Morning Star more effective in general combat - but unable to overwhelm opponents in close combat as quickly as the standard mace. It's actually the longest "pure" 1handed weapon in the game. Along with the Holy Water Sprinkler, Flanged Mace and Grand Mace , it is one of the three weapons that deal Blunt/pierce damage.
The Morning Star's low speed but long reach make this weapon much more defensive than the other maces; allowing its user to play a solid close range game at the cost of it's ability to overwhelm foes. Thus, this weapon benefits from the use of a shield and greatly increase the weapon's efficiency with a semi-defensive playstyle. Its rare pierce-blunt typing and solid damage makes it a very effective weapon to use on enemy vanguards and knights.
The Morning Star's length and damage makes it a solid weapon to stab with, particularly with Knights and Vanguards.
Due to patches, the description is no longer true; it actually does damage on par of a traditional mace , and trades swing speed for reach. (confirmed).
