Today I had the revelation that my half orc has 30ft speed, but because she’s a monk, her unarmored movement is +10ft at Level 3. Using the ki feature Breath of the Wind, she can dash as a bonus action meaning she can go 80ft in a turn.
If anyone cast Haste on my dear sweet Marfu, she would go 160 in six seconds.
At her most perfect Level 20 self’s unarmored movement of +30, she could go a max 120ft in a turn, or 240ft hasted. With 20 ki points to spend that could mean a solid two minutes of going almost 30 miles per hour and I think that’s beautiful.
