The breath is an area attack affecting every creature in a cone 10 meters long by 5 meters wide for a Medium or Large creature (Huge: 20 by 10 meters; Colossal: 30 by 15 meters). The attack automatically deals (no attack roll) [(CR+2) x 1d6] damage (for example 6d6 for CR 4). Damage is halved if the victim succeeds on a DC 13 Dexterity check. The creature must wait 1d4 rounds before using its breath again after each use. For simplicity, once damage exceeds 6d6, each additional d6 is replaced with a +3 bonus. So a CR 14 dragon's breath deals [6d6 + 30] damage.

The creature gains an extra movement action per turn while flying. On the first round of combat, the creature gains a +5 bonus to attack rolls and +1d6 damage if it is flying and attacks a creature on the ground.

On an attack roll result of 15-20 on the d20, the creature grabs its prey and does not let go. It gains a +5 bonus to attack rolls and +1d6 damage against the creature it is grabbing, which is Restrained if it is smaller than the dragon. The victim can attempt to break free by spending a movement action and succeeding on an opposed Strength check.

The creature can carry a grabbed victim smaller than itself into the air by spending a movement action. On the first round, if the victim breaks free (opposed Strength check), it takes 5d6 falling damage. On the following round, if the creature chooses to gain altitude, the damage increases to 10d6.

On an attack roll of 15-20, if the attack succeeds, the victim must succeed on a Strength or Dexterity check (its choice), DC [10 + the creature's Strength modifier], or be Knocked Prone. The creature reduces all weapon damage it takes (melee or ranged) by 2 (damage reduction 2). Spells deal normal damage.

The creature uses its great size to affect several creatures in front of it with a single blow. If multiple targets are in front of it, its attack affects two creatures (in a 180° arc). Make a single attack roll and compare it to each target's armor class. Its damage reduction increases to 4.
