We're getting all sorts of interesting information from the ongoing D&D Experience out in Virginia, but here's something that stopped me in my tracks.
As you can see, Eladrin can apparently teleport 25 feet once per encounter. As a racial ability.
I've looked at that damn link like five times now, and am still at a loss.
Man, I would break the hell out of an Eladrin rogue.
To review: Elves (at least these (Non-Wood) Elves), whatever name you want to give them, High Elves, Eladrin) can now teleport. I can only surmise, somewhere back in that family tree, Nightcrawler and Arwen got it on.
