I generally avoid talking about specific game systems, but recently I started a D&D 5E game and I have some experience that can help you in building characters. In one short game, I had our monk character go up against a friendly monk NPC in a fighting match. During the fight the PC had an ability to cause disadvantage and no matter what I tried, I could barely hit the PC. This allowed the PC to overcome the superior NPC―and could allow you to do the same. First, let's do a quick review.
