He's a melee Slayer, that's the problem.
If you play as a Lich and recruit Delemare, she'll be a ranged Slayer and work much better because of that.
Honestly, the only way to make Greybor usable is to build him as a off-tank, following the Freebooter or Ranger Demonslayer class. Have him focus on Kukris, pick that one with multiple elements in Areelu's lab, and use Elemental Barrage. THEN you'll have the assassin character he deserves.
