Notes from author
[Credits to DarkSoulsMindEye for the build idea.]
This build was essentially made for swapping weapons in the middle of a fight. Sure, you can use a standard Zweihander and Longsword, but the Zweihander is meant to be swapped out with any weapon with special properties. That is, any boss weapon with an AOE or a special RT/R2 (Dragon Weapons, MLGS, Stone Greatsword, Obsidian Greatsword). It's easy to trick your opponent with this build, and, well... it's purely fun and destructive. You can do hilarious little combos as well, such as casting the TWOP-like spell with the Stone GS, then swapping to a 2H Stone Greataxe for some easy RTs/R2s that will smash your opponent into the ground or send them flying in the air. Just an overall exciting build if you're into doing random invasions or Forest invasions. Make sure you carry plenty of Repair Powder, because you'll likely be doing a ton of strong AOE attacks, which eat right through durability.
