A subclass for the monk that is focused on speed and your feet.

Speedy Feet

Starting at when you get this subclass, using your speedy feet, you can disengage and dash without expending any ki points. 

Aura of Haste

Each ally within 30ft of you gets a +5ft bonus to their speed that turn. This bonus increases to +10ft by level 11 and +20ft by level 19. The bonus only applies to those who start their turn in there.

Initiative Bonus

When initiative is rolled, you may spend 3 ki points to change your place, or to gain an extra turn at the end of the first round of combat. The two cannot be used in the same combat.

Trail of Ice

Your feet leave a trail of ice that lasts for 5 turns. To do this, you must spend a minimum of three ki points. Anyone who tries to walk on the ice must succeed on a dexterity saving throw of 8 + your proficiency bonus + the amount of ki points you spend on top of the normal three. A failed save results in falling prone. Additionally, anyone who is within 10ft of you takes 8d10 cold damage unless you prevent them from it. This can affect multiple people. This trail can only be made where you use your movement, but does not take up your action.
