The mystic from Unearthed Arcana can get an ability called there and back again that states
There and Back Again (2 psi): As a bonus action, you teleport up to 20 feet to an unoccupied space you can see and then move up to half your speed. At the end of your turn, you can teleport back to the spot you occupied before teleporting, unless it is now occupied or on a different plane of existence.
Now this states it is a bonus action to teleport AND move half your movement speed. If I am correct in understanding this that means you can (with standard 30ft movement) teleport 20ft, move 15, move action for 30 more, then action dash for 30 for a total of 95ft distance in a single turn. Then of course pop back like nothing happened.
Is this a correct assessment or does the ability also burn your movement action?
Best Answer
The ability gives you extra movement.
First, note that there is no "movement action" in D&D 5e. On your turn, you can move up to your speed and take an action; these are separate things.
Second, note that the Mystic isn't official, so the rules language in some of the abilities isn't as tight as you would find in published material.
The phrasing here is unusual, but following the general principle that abilities do what they say, I would assume that a Mystic using There and Back Again on their turn could do the following, in any order:
And at the end of their turn they may return to the space they teleported from. If they took the Dash action and moved as described in the question, they could indeed reach a point 95' away before they teleported back at the end of their turn (or remained in position, at their option).
