Or, it could sloppy reuse of text from prior editions! That gets my vote.While teleportation instances in 5e (that I have found) don’t use the word “simultaneous,” they do use words like “instantly” (one of the common definitions of “instantly” is “immediately,” which is the same word used to describe when the thunder occurs in the spell). Since 5e doesn’t rank these minuscule measurements of time (instantly, simultaneous, immediately, etc.), I can’t see it plain English for them to have to be arbiltrarilly ranked by players/DMs or differentiated.
I used Misty Step as an example above of why Thunderstep shouldn’t prevent damage; I’m not saying MS could be used that way and was careless in the action economy (because that wasn’t the point).
Hmm, the wording of Dimensional Shackles confuses me even more. That description says the shackles prevent “extradimensional movement, including teleportation or travel to a different plane of existence.” That makes it sound like teleportation is extra dimensional travel but not travel to a different plane. In that case, what does extradimensional mean? One definition is “outside of space-time reality.” That could mean in a dimension other than the standard, but if that were the case here, it doesn’t make sense to add “or travel to a different plane if existence.” Or it could mean, outside of space and time; that could support the idea of no time passing during a teleport.
Or it could be “teleportation or travel” could be 2 different modes to get to another dimension (“or” joining the word on either side of it rather than separating “teleportation” from the phrase “travel to a different plane of existence”). In this case, Teleportation is just a mode that could be used to get to another dimension or to move within 1 dimension: Teleportation itself does not rely on inter-dimensional travel but could be used to do so.
That text directly and unambiguously implies that teleportation is a form of interdimensional travel. However, that idea seems well scrubbed from the description of the teleport spell.
