The weapon i used here is Channeler's Trident. The tip of the trident spins while hitting an opponent (One-Handed Strong Attack), hitting them three times. Works really well with poison or bleed. Link to the weapon is below.
"Velstadt was always at the King's side, as if he were his lord's own shadow. After the King retired to the Undead Crypt, Velstadt followed, never to return. "
