I've been developing a Samurai class inspired by Final Fantasy 14 for a DND 5e homebrew (my own take), and I'd greatly appreciate your feedback. I've already designed one subclass, and I'm in the process of creating another. Since this is my first attempt at modding, I expect there may be some bugs and balance issues, so any suggestions or insights you have are more than welcome. Additionally, if you think of any other potential subclasses that could complement this Samurai class, please don't hesitate to share your ideas.

If you start with a new game your equipment will include a katana (in-game model) similar specs as Basket Full of Equipment Shadow Katana by AnteMaxx. I have been trying to get the animation of a shadow monk holding a sword however can't seem to find the trigger for it so at lvl 3 respect to shadow monk and back to have a cooler stances.
