This is a fighter subclass that I created to fill that hole at not just a fighter that does more damage in cool ways but one that survives, posters, and uses opportunity to attack instead of brute force. I wanted to create a subclass that allow more tactical thought and resource use like a monks Ki point but as focus points. I wanted to also wanted to focus on single person fighting and picking apart that BBEG without the feeling of cheap abilities like stunning strike or anything that completely immobilizes the enemy. I am a big fan of the Legend of Drizzt and hoped to do his character justice with this subclass
