"A rogue of 8th level or higher can no longer be flanked.<br/>"<br/><br/>That sounds pretty straightforward. It goes on to state that he doesn't lose his dex bonus to AC, which means that he keeps his dodge/nimble bonuses to AC.<br/><br/>Admittedly, it says nothing about the attack bonus to flanking creatures, but overall, the AC doesn't sufer, which is the usual advantage to flanking; being able to hit a target because he's lost some of his AC.<br/><br/>So, the worms keep their +2 attack bonus to flanking, but Andru keeps his full AC and he can't be caught flat footed.<br/><br/>If Uncanny dodge works ONLY against sneak attacks, I've seen a lot of people miss-using it.
