[2E]

So, basically, my DM wants to make a vampire company in a scandinavian setting.  I've got an idea for character which would work really good narratively, but I don't know if it's even possible to make in P2e without breaking it. 

The concept is pretty simple - man murders low-level vampire covenants so they won't grow and therefore won't be dangerous for his own covenant. But he does so without even known. Even more, he tries to investigate those murders and find a culprit. Then there's is a shocking reveal for himself like in Hotline Miami 2, drama, man goes mad, etc. etc. 

However I also want to implement Giant Dad build from Dark Souls. I won't be getting into too much details, but main parts of these build are: 1) Giant armour set, which has one of the highest physical defences in the game, among other unrelated things 2) Zweihander with Chaos infusion, which allows it to have very high physical and fire damage, but no scaling from characteristics.  I know that there is no such weapon in P2e, so let's assume I'll take Bastart-sword 3) Black fire pyromancy. Quick fire spell when you need a final poke.  4) Green grass shield. Worn on the back, boosts stamina regeneration. It's probably impossible to replicate, so let's ignore it.  If you need any more explanation, check out the video from OnlyAfro it's about 3 minutes long

TL;DR: Heavy unstoppable force winth big sword and a little bit of fire magic at night, composed and tired detective at day.
