Thanks, that clears that up. I guess you could still make four ranged attacks in a round if you started your turn with two weapons, threw them, then quick drawed a couple more and threw them, but of course you could already do that without mind daggers. I guess I figured that as long as you had one dagger you could reform your mind blade into it's one-handed shape and back into daggers, but I guess needing both daggers to switch back makes more sense.

Sorry, I've just got a game starting before too long where I'll be playing a Soulknife with a very experienced, high optimization group that lets a lot of cheese work so long as it's RAW, and I want to know what I'll be able to get away with.
