Magic Rider

So, how does the Elf ancestry feat Magic Rider

Quote:

Your people used powerful magic to travel between distant worlds in the distant past, and the remnants of that magic make such transportation easier for you. When you are the target of a teleportation spell that transports more than one person, it can affect an additional person beyond the normal limit, chosen by the caster. Additionally, when you're the target of a teleport spell, you and the other targets arrive no farther than 1 mile off target, regardless of distance traveled.

work with the spell Unexpected Transposition

Quote:

Cast [reaction] verbal; Trigger You are targeted with an enemy's Strike.

When attacked, you attempt to quickly swap your own position with that of another creature. A creature that is unwilling to swap places with you must attempt a Will save. Willing creatures automatically fail. If you successfully switch places with the target, the triggering attack is resolved against that creature as if it had been the original target of the attack. After the swap, you and the target are both temporarily immune to unexpected transposition spells for 1 minute. You automatically switch places if the target is willing. If it's unwilling, it can attempt a Will save. Neither of you teleports if the target succeeds at its save.

since the spell does indeed teleport more than one person?

[Errenor]

Nominally you aren't the target of the spell so we can stop thinking about it. The one target is another creature, willing or not.
Well, unless the target IS (another?) elf with Magic Rider. Well, there we have two solutions: either it still won't work because it doesn't make sense or spell puts two people in your place: one to take the attack and one in an adjacent square. GMs can choose.

Despite being teleporting by it, that spell does not target the caster so nothing extra happens re: the caster being a Magic Rider.

If the Magic Rider is the one begin swapped in to be attacked, I guess they could get somebody else to come along IF the caster chooses them too (which enemies likely wouldn't know to do) and if the other target fails their save (or is willing, which implies an understanding of what's occurring, which seems a tad contrived, but could happen w/ planning). Then we'd enter fringe areas, since I doubt anybody would rule they share the same space or both receive the Strike. So yeah, there'd be another PC alongside (or BBEG sacrificing some explosive minions. Bwah, hah, hah!).

So in a contrived tactic, one caster could teleport one Magic Rider ally and another ally into danger for the price of a 6th rank spell (and if the Magic Rider were a Swashbuckler/Pain Cleric or such, there might be a benefit to this even). But I don't see enemies or unprepared allies enabling this.
