Far Thoughts. The dragon is aware of any creature that uses a psionic ability or communicates telepathically within 100 miles of it. As an action, the dragon can psionically observe a creature, object, or location it is familiar with within 100 miles. While observing a subject in this way, the dragon can see, hear, and communicate telepathically, but it is blind and deaf in regard to its physical senses and does not require food or water. The dragon can psionically observe a subject indefinitely and can end this effect and return to its own senses as an action.
ACTIONS
Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 13 (2d10 + 2) piercing damage.
Concussive Breath (Recharge 5–6). The dragon psionically unleashes telekinetic energy in a 15-foot cone. Each creature in that area makes a DC 12 Constitution saving throw , taking 16 (3d10) force damage on a failed save or half damage on a success.
Combat
While individual dragons have their own personalities and tactics, most rely heavily on their breath weapons. They use them whenever they can, preferably from maximum distance and while flying above their enemies.
When fighting in the open, dragons often circle above their enemies as they wait for their breath weapons to recharge. They only close to melee if their enemies deal significant damage with ranged attacks, or if they can savage an enemy cut off from its allies. Once bloodied , dragons become more aggressive, attacking with bite and claws when their breath weapons aren’t available.
If a dragon is protecting its lair, it utilizes lair features, traps, allies, and architecture such as escape tunnels to keep up a hit-and-run fight, reappearing only when it has a fully-recharged breath weapon. If the dragon is forced into melee combat, it uses its bite and claws against a single foe. If it has legendary actions like Roar and Wing Attack, it uses them to disperse its other enemies.
If reduced to less than one-fourth its hit points while fighting in the open, a dragon flies away. However, it fights to the death to defend its lair, unless it can regain the upper hand through tricks or bargains.
Amethyst Dragon Lair Features
The save DC for the following effects is 13 + the dragon’s proficiency modifier. Choose or roll one or more of the following lair features:
1 The lair hosts many charmed or willing servants. Once per day when the dragon would use Charm, it can summon 3 cult fanatics instead. Creatures summoned in this way fight until killed or until the dragon dismisses them as a bonus action.
2 Psionic illusions mask several passages through the lair. Spotting these illusions requires a successful Perception check against the lair’s DC. Physically interacting with an illusion also reveals its nature.
3 The lair resonates with the dragon’s psionic powers. The range of the dragon’s psionic abilities is doubled.
4 The dragon’s words seem to ring true amidst the opulence and grandeur of its lair. Insight checks made to determine the dragon’s true intentions have disadvantage .

Legends and Lore
With an Arcana or History check, characters can learn the following:
DC 15 Like all gem dragons, psionic dragons boast powerful psionic abilities. They can communicate telepathically and exhale powerful blasts of telekinetic force.
DC 20 Ancient amethyst dragons can control the weak-willed using the power of their minds alone.
Though still reclusive by draconic standards, amethyst dragons are the most diplomatic of the gem dragons. They favor nonviolent negotiations, but even deals they make in good faith seem to end in their favor. They make their lairs welcoming to humanoid guests and are always eager to resolve a conflict with words before resorting to talons or the earth-shattering force of their breath weapons.
Master Manipulators. To meet an amethyst dragon is to become its puppet. The moment it becomes aware of a creature, the dragon is already plotting to thwart the creature’s plans or claim it as a pawn. An amethyst dragon’s only saving grace is its lack of malice. Rarely does an amethyst dragon kill its foes outright, considering such violence a needless waste of resources. Instead, it seeks to turn each situation to its advantage—and occasionally to the advantage of its allies as well.
