Notes from author
Never done this kind of build before, so advice is very much appreciated.
The armor is just what I think would look good and not optimized for protection. It's not an essential part of the build so it can be replaced depending on user preference.
I like using the DWG ring, others don't. If you're one of those people, then I personally recommend the Cloranthy or Red TS ring as a replacement.
Make sure to always have atleast 10 humanity at all times to keep the Chaos shotel effective. Keep the Claymore equipped with CP resin, or GP resin if you'd prefer that. (Honestly GP resin is probably a better choice, but CP looks cooler, plus it fits the whole berserker theme rather well imo.)
Lastly, make sure not to ascend your pyro flame. Doing so causes Power Within to drain your health faster, which can really make a big difference when invading since you can't heal yourself.
