Base Class: Monk
Speed
Unarmored Sprint
When you are not warring armour, holding a shield or a weapon without the light properly, your base speed is multiplied by your proficiency bonus. Additionally, you have advantage on any effect that reduces your speed.
At 6th level, you no longer use a ki point whilst dashing as a bonus action.
Misdirection
At lv6 you can move so fast that you can be in two places at once. By using between 1 to 3 ki points you can create that many clones.
Each clone shares your stats but can’t take actions other than the dash or doge actions. Each clone has HP equal to your monk level x2.
These clones disappear after a minute.
Regeneration
Starting at lv11 when your HP is below half, you can use the ‘Quickened healing’ monk feature without using an action at the start of your turn.
Unleash
Once per long rest you can unleash yourself to move at your top speed. Roll 1d4+1 the number rolled is the number of turns you immediately take. At the end of the final turn, you take levels of exhaustion equal to the number of turns taken.
Thanks, I’m dyslexic n struggle with wording/spelling I’ll update it when I have time (prob will forget)
An interesting take on the likes of types of characters like "The Flash", and an interesting addition to 5e. A note, "Warring" should be changed to wearing, "properly" changed to property. (Unarmored Sprint), "doge" should be dodge (Misdirection).
