The way this Build works is that you'll buff your Rapier or Estoc with Scholar's Armament to double your melee damage or so early on, allowing you to one or two shot most enemies. Make sure that you have both your Staff and Weapon out at the same time or you won't be able to buff it. You can use Glintstone Pebble to thin enemies when their are many to prevent yourself from being swarmed, and also to hit enemies that you can't get to physically.

Carian Slicer is your money maker and makes short work of Bosses and challenging enemies. You'll spam this repeatedly when you get openings to melt Boss HP. It's absolutely devastating. Just know that you deal almost no Stagger with this Spell so you will have to read enemy ques and dodge when they begin to retaliate.

You can use a Shield in some scenarios where Blocking is beneficial, but it rarely is since it drains your Stamina when Blocking and you need it to attack rapidly with Carian Slicer.
