The way this Build works is that you'll buff with Golden Vow and you'll Block Counter as necessary. You'll use Bolt of Gransax as your primary weapon, dealing Physical and Lightning Damage, only swapping to Cleanrot Spear or Treespear when enemies resist Lighting Damage. Since you're using a Shield and Spear you can Block and attack at the same time, protecting yourself from attacks while also dealing damage.

You'll use Ancient Lightning Spear to pick off enemies at range as needed, particularly difficult enemies that can be killed quickly with it, or using it against Bosses when melee is not the best option. Ancient Lightning Spear hits much harder than the Lightning Spear Incantation, and costs about the same FP with this setup, and has much more range as well. You can charge it up for extra damage if you want, or just use it regularly when you don't have the spacing or time to do so.

This Build is a great blend of offense and defense because you can lead with Ancient Lightning Spear and then Block and attack or Block Counter for solid damage in melee when enemies get close. It's also very hard to kill because it can block very easily.
