Rather than make Weapon Throwing a standard action, why don't we make it a full attack action, like we did for bind wings? That would keep them from iterative attacks. Plus it makes somewhat more sense for an attack. I'm going to make the updates like that, so we can see how it looks (we can always change to standard action later).
I'd prefer to keep it a standard action. That way they can also take a move action and throw the weapon on the move - which is something people often do in the real world when trying to add range and impact to their hurled objects.
Come to think of it, I'd prefer both Bind Wings and Stifle Breath to be standard actions. We allowed Dazzling Display to be used as a standard action, and that probably involves a lot more twirling of weaponry than Bind Wings and Stifle Breath, which could just be a matter of hitting the dragon once in just the right way.
Actually, I'd consider cutting the "standard action" from Dazzling Display and just leave the "part of a full attack action" bit, then we can make the "Improved Dazzling Display" the one that allows it to be done as a standard action. Also, we might have the Improved version having a reduced attack penalty.
I have a suspicion when we finished Dazzling Display we just copy-and-pasted the text to use as the basis for some of the subsequent special attacks, which is how it got a bit messy.
I've put in some tactics also (just to move this along

), so see what you think.
Updated (finished?).
Well, sample creature for a template don't require a tactic entry, but if you want to add some there's no reason we can't.
The tactics look fine to me, except I'd add something about it using the
haste power of its
boots of speed.
