Mindstalker

Never faltering in their task, the mindstalker is a fierce hunter of psionic aberrations. Armed with the same psionic ability that many of these aberrations use to take advantage of their prey, these rangers relentlessly seek their targets, turning a careless predator into unsuspecting quarry. Those wary enough to know of a mindstalker's existence and skill set wisely respect them, and often fear them.

Mindstalker Magic

Starting at 3rd level, you learn an additional spell when you reach certain levels in this class, as shown in the Mindstalker Spells table. The spell counts as a ranger spell for you, but it doesn't count against the number of ranger spells you know.

Ego Piercer

At 3rd level, you can imbue your strikes with psionic energy that seeps through wounds and strikes at the mind.
You can use your bonus action to cause your next weapon attack that hits before the end of the turn to deal an extra 1d8 psychic damage. If a creature capable of telepathy takes this damage, it must succeed on a Wisdom saving throw against your spell save DC or be frightened of you until the start of your next turn.

Empath Sense

Also at 3rd level, your mind is keenly tuned to detect the presence of other psionic beings.
You know whenever a creature speaks via telepathy while within 60 feet of you. Also, you can use your action to attempt to weed out the presence of telepathic creatures within 300 feet of you. Any creature within range that is capable of telepathy must succeed on a Charisma saving throw against your spell save DC or you become aware of its presence and its distance away from you. Once you've used this action, you must finish a short or long rest before you can use it again.

Lucid Buffer

At 7th level, your consciousness is firmly rooted, making it difficult to control you. You have advantage on saving throws against being charmed, frightened, and stunned.

Cerebral Blind

At 11th level, you slip into the blind spot of minds attempting to divine you, becoming an undetectable presence.
When any manifestations, spells, or other effects attempt to divine information about you or your location - such as the arcane eye, locate creature, or scrying spells, or the manifestations find creature, view aura, or unwavering eye - the attempts fail if you are the target, and you are invisible to sensors created by these effects.

Blast Feedback

At 15th level, afflictions of the mind have little effect on you, and you can even turn certain effects back onto your attackers.
You have resistance to psychic damage, and whenever a creature forces you to make an Intelligence saving throw for a manifestation, spell, or effect, your mind partially reflects the assault, forcing the originating creature to also make the saving throw or suffer the same effects it is attempting to inflict upon you.
