This is being specially challenging for me.
If there is one thing that I love doing with classes and races in D&D5e is tweaking the classes and races into something that feels new using the suggestions in the DMG.
I'm finding the Avenger specially challenging, though. I have an idea of how making it happen but I'd love to have an answer here that would point me to the right direction at least and hopefully, give me a solution to the problem.
The major problems with the Avenger are the following:
Their sword is directly guided by their god, therefore they could use a huge weapon without the need of Strength (They'd use WIS for attacks, AC and spells), but in 5e, they'd need Strength to be able to use a huge weapon, making them lack a decent AC. Avengers are not supposed to be strong, but they need to be deadly. It's their signature having a huge weapon plus and decent defense, plus they need to have some spark of divine powers (not healing ones, though, but things like "Turn Undead" that makes them feel kinda like clerics. They're supposed to be like inquisitors, I'd say). I've tried tweaking the cleric and the Avenger Paladin but nothing feels balanced enough.
So, how do I tweak a class (and what class) in a way I can make my player actually feel like he is playing an Avenger? What kind of tweaks should I make and what class should I use as baseline?
I expect something like the guide I made for the Invoker.
