Why Great Old One Patron?
As a Great Old One Warlock, your job is to control the battlefield by messing with your enemies' minds. Combining this cosmic power with a Halfling's natural traits creates a surprisingly durable and slippery spellcaster. Thanks to your Luck racial trait, you rarely have to worry about critically failing important spell attacks or saving throws, ensuring your mind-warping magic lands when your party needs it most.
Furthermore, Halflings excel at staying out of harm's way. Your Halfling Nimbleness allows you to weave through the space of larger enemies to find the perfect vantage point. Once positioned, you can unleash features like Awakened Mind, letting you project silent, telepathic thoughts straight into the minds of creatures nearby without revealing your location. If enemies do manage to corner you, your Halfling Brave trait helps you resist fear effects, keeping you focused and in control.
Ultimately, this combination turns the squishy Warlock into a master of psychological warfare. You can easily hide behind your beefier allies, manipulate the minds of your foes from afar, and shrug off the mental attacks of enemy spellcasters with ease.
Great Old One Patron Features
Awakened Mind
Level 3You can communicate telepathically with any creature you can see within 30 feet. You don't need to share a language for the creature to understand your telepathic messages, but the creature must be able to understand at least one language.
Great Old One Spells
Level 3You gain additional spells that count as warlock spells for you: Dissonant Whispers, Tasha's Hideous Laughter (level 1); Detect Thoughts, Phantasmal Force (level 3); Clairvoyance, Hunger of Hadar (level 5); Dominate Beast, Evard's Black Tentacles (level 7); Dominate Person, Telekinesis (level 9).
Psychic Spells
Level 3You learn additional psionic spells that count as warlock spells for you. These spells allow you to invade and manipulate the minds of your enemies.
Clairvoyant Combatant
Level 6When you deal damage to a creature, you gain advantage on attack rolls against that creature until the end of your current turn, as you peer briefly into its immediate future. Additionally, that creature can't make opportunity attacks against you for the rest of that turn.
Eldritch Hex
Level 10When you place a curse on a creature (such as with the Hex spell or a warlock feature that curses), you can use a bonus action to give that creature disadvantage on saving throws against one ability of your choice until the curse ends.
Thought Shield
Level 10Your thoughts can't be read by telepathy or other means unless you allow it. You also have resistance to psychic damage, and whenever a creature deals psychic damage to you, that creature takes the same amount of psychic damage.
Create Thrall
Level 14You can use your action to touch an incapacitated humanoid. That creature is then charmed by you until a Remove Curse spell is cast on it, the charmed condition is removed from it, or you use this feature again. You can communicate telepathically with the charmed creature as long as the two of you are on the same plane of existence.
