If a Strike has the deadly trait, how does that trait interact with the Strikes of high level monsters that don't rely on striking runes?
For instance, the ancient cloud dragon has this horn attack.
Melee [one-action] horn +34 [+29/+24] (deadly d12, magical, reach 20 feet), Damage 3d12+17 piercing
Does a critical horn Strike deal only 2*(3d12+17)+1d12 because the horn has no greater/major striking runes?
Actually, never mind. The extra dice for the deadly trait are apparently included in the trait for the relevant monster Strikes.
Melee [one-action] jaws +36 [+31/+26] (deadly 3d10, fire, reach 20 feet), Damage 3d10+18 piercing plus 2d6 fire and Improved Grab
