You can run along walls when taking the Dash action. You maintain your wall-bound position until you don’t take the Dash action. This effect can persist for multiple turns. You can also jump between two walls that are within close proximity. “Close proximity” means within a number of feet equal to your Dexterity score (minimum of 10 feet). The number of times you can jump between the same 2 walls =2 times your Dexterity modifier + your proficiency bonus.
