Dimensional Agility states that you can take your other actions as normal after casting dimension door.
Mythic dimension door says that you create a portal in your space that allows you and creatures you designate to use the portal to teleport to another specified space within range. You use the portal immediately when you cast it and anyone else can run through on their turn.
What if you use the portal to teleport ~100 feet away and then a couple round's later you run back to your portal and teleports back to the destination space? Could you continue to act?
Which one do you think:
A) mythic dimension door is a different spell and this doesn't work at all.
B) dimensional agility works on the initial teleport, but not subsequent portal uses since the feat says "when you cast dimension door" and not "when you teleport using dimension door" or similar.
C) dimensional agility works whenever you walk through your dimension door portal.
D) as above except with any dimension door portal that you are allowed to walk through.
E) dimensional agility works for every portal use on the round on which you cast the spell, but not later rounds.
F) other
I've been discussing with friends and we'd love to hear some other opinions.
