Speed is your freedom

Prerequisites: Dexterity 15, Strength 14, 12th level.
For some, speed is a tool. For you, it is the ultimate expression of freedom. You have pushed your body beyond its limits, reaching a level of mobility and reflexes that few could even comprehend.

• Increase your Strength or Dexterity score by 1, to a maximum of 20.
• Your movement speed increases by 15 feet.
• You gain two reactions instead of one during each round of combat. If you use one of those reactions to cast a spell that takes 1 reaction to cast, you can't use your other reaction to cast another spell during the same round.
• If your movement speed is at least 70 feet, you can run along walls and across the surface of water while moving.
• When you take the Dash action, your jump distance equals your movement speed.
• Once per long rest, when you take the Dash action, you can use a bonus action to triple your movement speed until the end of the turn.
