[RPG] the correct way to use Disengage or Dash as a bonus action

dnd-5emovement

We've been playing for a couple of years and this has been the usual playstyle of our Rogue:

  • Move his speed (30ft) until in melee range of enemy
  • Attack
  • Disengage as bonus action, and move 30ft away from enemy without triggering opportunity attacks (OAs)

But, while reading a related question, I realized that Disengage doesn't grant you additional movement. It instead applies special traits to the movement you already have. Instead, the Rogue must do something like

  • Disengage as bonus action (this can be done anywhere before the final movement part)
  • Move half his speed (15ft) until in melee range of enemy
  • Attack
  • Move 15ft away from enemy without triggering OAs

What is the correct way to use Disengage as a bonus action?

What if our main actions are also a Disengage or a Dash? I'm guessing that

  • Dash + Dash = Wasted action
  • Disengage + Disengage = Wasted action
  • Disengage + Dash = double speed without triggering OAs
  • Dash + Disengage = double speed without triggering OAs

Is this interpretation correct?

It's almost correct

You can take multiple Dash actions, as many as you have available (whether by your action, bonus action, action surged action, Hasted action, etc). It has the effect of increasing your available movement on that turn by an amount equal to your Speed, and so they stack.

  • Dash (A) + Dash (BA) = movement equal to thrice your speed

  • Disengage (A) + Disengage (BA) = Wasted action

  • Disengage (A) + Dash (BA) = double movement without triggering OAs

  • Dash (A) + Disengage (BA) = double movement without triggering OAs

The difference between "speed" and "movement" is almost pedantic, but it is sometimes important. Your "speed" is the name of your statistic, normally determined by your race, and can be enhanced by spells, items, or feats. A human with the Mobile feat and Longstrider has a speed of 50ft.

"Movement" is the distance you have left that you may cover after subtracting all the distance you've already moved from your speed. So if you have used up 30ft of movement on a character with a speed of 50ft, you have movement left equal to 20ft.
