So I was reading Xanthir Vang's statblock, and I noticed some things that didn't Make sense to me.
The speedy summons path ability is in the first tier list, but it says that you must be at least 3rd tier to select it. If you do have to be 3rd tier, then Xanthir has 3 3rd tier abilities and only one first, which makes no sense because then he would have to take a 3rd tier ability at 2nd tier. Also, the second part of this ability is rendered completely redundant by the arcane surge Archmage arcana, which is also ridiculously OP, even for mythic. Also, Xanthir has used 2 uses of mythic power to cast augmented mythic fly, but he could do the same thing with just one use of his mythic spellpower ability, which is, as far as I can tell, a better move all around.
Finally, I also noticed Arueshalae is listed as having +3d6 sneak attack, but level 6 of master spy has only +2d6, and I don't see any other source for that last die.
I've also noticed that Marhevok has some missing/incorrect stuff too, so I've rebuilt him to have those things, better reflect his theme, and look more like his picture.

This statblock assumes that Marhevok rages and uses enlarge person. Rage, all abyssal blood rage powers, and the lesser fiend totem rage power have been factored into Marhevok's statistics.
Also, Svennarobeth's bite attack should deal 1d6 damage, not 1d8
Yeah, that's what I figured :) They're pretty easy fixes.
