Could someone detail the full calculation for Karzoug's HP in the RotR Anniversary Edition?
His HP is shown as 20d6+310, but as I see it he should add +180 from Con., +60 from ioun stones, +20 from Toughness feat, and +20 from false life (at most)for a total of 20d6+280. What am I missing that adds the extra 30 HP?
