The most common homebrew changes I’ve seen people make for monks is making things like ki = level + wisdom, hightening their damage die on each step (D4 to D6, D6 to D8, etc.) and, to a lesser extend, raising their hit die to a d10.
For people who have done all or at least two of these changes at once or have experienced another player do that, how did it go? I’m genuinely curious!
What I did for my monk’s is that they have a ki point pool equal to their monk level times their proficiency bonus. Not only that, when they flurry of blows, they can strike their targets a number of times equal to their proficiency bonus.
Now pair that with the fact that I give all my players the ability to take another action or bonus action on their turns and you get some crazy stuff. By level 5, the monk would have 15 ki points, can attack twice with extra attack, 3 attacks with flurry of blows, and then 3 more attacks if they choose to do so again. And I recently gave the party the formula to make gloves of soul catching.
It’s a lot of fun!
