Magical Resistance. The dragon has advantage on savingthrows against spells and other magical effects.

False Appearance. While this dragon remains motionless, it is indistinguishable from a large boulder.

Multiattack. If the dragon makes a bite-attack it can make a claw attack onto the same target aswell.

Bite. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 14 (1d10 + 9) piercing damage.

Claw. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 13 (1d8 + 9) slashing damage.

Hurl Stone. Ranged Weapon Attack: +9 to hit, range 30/90 ft., one target. Hit: 17 (2d8 + 9) bludgeoning damage. Furthermore if the target is hit, it has to make a DC 20 Strength Savingthrow or becomes Prone. If the creature is able to fly via the means of wings, the creature also looses the ability to fly for 1d6 rounds.

Breath Weapons (Recharge 4–6). The dragon uses one of the following breath weapons.

Forcefull Breath. The dragon exhales pure force energy in an 60-foot cone. Each creature in that cone must make a DC 20 Dexterity saving throw, taking 24 (8d8) force damage on a failed save, or half as much damage on a successful one. If the target of the breath weapon is a dragon or dragon adjacent, or considered a dragon, it has to make a DC 20 constitution savingthrow. On a failed save the target gets disintegrated, when this breath weapon reduces the target to 0 HP.

Magical Adversity (Recharge 4–6).If the dragon is targeted by a magic missile spell, a line spell, a spell that requires a ranged attack roll or any breath weapon, the dragon can choose to absorb the spells magical energy. The dragon therefore is unaffected by the magic effect or breath weapon and said magic effekt or breath weapon is reflected and targets the caster as though the spell or effekt originated from the dragon.
