I was playing a game of D&D 5e the other day and got into a disagreement with the DM. I have a monk character that made a long jump off a wall using Step of the Wind. The plan was to do Flurry of Blows after landing, but the DM said that I couldn't use Flurry of Blows because I had burned my bonus action on Step of the Wind.
The description of Step of the Wind in the monk's Ki feature says:
You can spend 1 ki point to take the Disengage or Dash action as a bonus action on your turn, and your jump distance is doubled for the turn.
My DM said that I have to take a bonus action before getting the jump bonus. I believe that taking a bonus action is optional and you can get double-jump without using a bonus action.
When you are in dim light or darkness, as a bonus action you can teleport up to 60 feet to an unoccupied space you can see that is also in dim light or darkness. You then have advantage on the first melee attack you make before the end of the turn.
The description of Flurry of Blows says:
After you take the Attack action on your turn, you can spend 1 ki point to make two unarmed strikes as a bonus action.
You can see that Shadow Step says that "You then" (after teleporting), and Flurry of Blows says that "After you take the Attack action". If you go back to "Step of the Wind", you can see that it doesn't say anything about your jump distance being doubled only after you Dash or Disengage as a bonus action.
Am I correct that Step of the Wind allows a monk to double their jump distance even without using Dash or Disengage as a bonus action?
