Normally, when a creature moves, they may choose to split up their movement across actions. For example, a creature can move 15 feet, attack another creature, and then move another 15 feet, all within the same turn, with a base movement speed of 30 feet per round.
Is the action required to move a Mage Hand permitted to split its movement up the same way?
For example, let's suppose an Arcane Trickster (which makes them able to move their Mage Hand as a Bonus Action) has got a Mage hand holding an object (like a stone) upon which I've cast the Light spell. I then try to take the following actions:
- I move 15 feet towards a target hiding in Darkness, whose location I know, but if I try to attack them, I'll get Disadvantage on the roll
- I use my Bonus Action to move the Mage Hand 15 feet forwards, illuminating my target (and myself) with Dim Light.
- I use my Action to attack the target.
- I move the Mage Hand back 15 feet, using the remainder of the movement permitted for Mage Hand, covering us both in Darkness again
- I move back 15 feet with the remainder of my own movement, avoiding the Attack of Opportunity because my target is no longer able to see me.
So the core question is, is step 4 legal? Or is that not permitted?
Note: This question is only about splitting up the movement on Mage Hand. This isn't an XY-Problem, and any comments or answers that try to address whether step 5 would resolve the way I've described are off-topic.
