Introduction
An eclectic mix of options, the Great Old One focuses on drawing power fromsomething unknowable and being appropriately crazy. Some of the abilities arevery potent, but just as many are situational and won’t see much use. The endresult is that the Great Old One Warlock (Often shortened to “GooLock”) feelsa lot like an Enchanter Wizard, but more spooky than the Fey Warlock.
It’s hard to say which warlock subclass is the most emblematic of the Warlock as a class, but I think the Great Old One might be it. The spells are a good mix of options, the features provide some excellent tools to handle a diverse set of challenges, and overall the spooky, cultish feel of getting power from an elder being just feels right for the Warlock. At the same time, the subclass isn’t especially complex, so it’s approachable for new players but satisfying for experienced players without being exceptionally powerful. Mechanically, it’s not a combat monster, but it can thrive in a variety of situations and fall back on core Warlock features in combat.
Playing a Great Old One Warlock requires more abstract thinking than your typical Eldritch Blast build. The subclass spells aren’t big offensive options, and the subclass features have little function in combat. Instead, you’ll find that you can approach problems less directly, often diffusing or subverting them before combat starts. Then at high levels you get to build an army of thralls. And who doesn’t love raising an army?

RPGBOT uses the color coding scheme which has become common among Pathfinder build handbooks, which is simple to understand and easy to read at a glance.
- Red: Bad, useless options, or options whichare extremely situational. Nearly never useful.

- Green: Good options. Useful often.
- Blue: Fantastic options, often essentialto the function of your character. Useful very frequently.
We will not include 3rd-party content, including content from DMs Guild, in handbooks for official content because we can’t assume that your game will allow 3rd-party content or homebrew.

Great Old One Warlock Features
- Expanded Spell List: A really diverse mixof debuffs, area control spells, and utilities. Weirdly, the only spells that benefit fromupcasting are Dominate Beast at 4th level and both 5th-level spells, so the spell list gainsalmost no benefit from Pact Magic’s unique scaling.
- 1st-level Spells: Two greatsingle-target control effects, but they will become obsolete beyondlow levels since they don’t scale with upcasting.
- 2nd-level Spells: Both options aresituational, but can be extremely potent if you’re clever.
- 3rd-level Spells: Clairvoyance is afantastic scouting option if you have a normal number of spell slotslike literally any other spellcaster, but Warlocks really need to savetheir spell slots for something more significant and impactful. Sendingis very situational, and you likely can’t justify using it on a day whenyou’re adventuring unless your party is willing to give you a short rest.
- 4th-level Spells: Dominate Beast isvery situational, especially since you won’t be running into many beastsby the time you can cast 4th-level spells. Black Tentacles is one of thebest area control spells, but may not be as encounter-ending as Hungerof Hadar.
- 5th-level Spells: Dominate Person isamong the best single-target control/debuff spells in the game,but it’s only situationally useful because humanoids are a small minority of the enemies thatyou’ll face in most campaigns.Telekinesis is a great utility, and you can use it to hoist melee-onlyenemies into mid-air.
- Awakened Mind: This is basically freepermanent Tongues combined with Telepathic Link. With high Charisma andaccess to Face skills, you can use this a lot.
- Entropic Ward: Not as reliable as othermechanics which respond to being attacked such as the Shield spell, butimposing Disadvantage makes you mathematically immune to critical hits, and,since your AC will likely exceed that of similar spellcasters like theSorcerer and the Wizard, you’re more likely to cause attacks against you tomiss.
Advantage on your next attack is nice, but, since it’s only on one attack,it’s minimally useful with Eldritch Blast, and there are very few spellattacks beyond cantrips in the Warlock’s repertoire. You might consider learning another attackcantrip like Fire Bolt specifically for use with Entropic Ward, but, unlessyou go Pact of the Tome it’s hard to justify spending one of your fewcantrips known on a combo that you can use once per Short or Long Rest.
- Thought Shield: Both effects aresituational. Psychic damage is extremely uncommon, but if you run into mindflayers you’re going to have a lot of fun.
- Create Thrall: This can be hard to use.Your best bet is to affect the target while they’re sleeping. Once you makethe target Charmed, the Charmed condition gives you Advantage on abilitychecks to “interact socially” with the creature, and, with a permanenttelepathic connection to the creature, you can easily talk it intodoing nearly whatever you want.
This isn’t a “dominate” effect, so you can’tprecisely control the creature’s actions, but you can talk it into takingspecific courses of action (bring me that thing, tell me what you see, spyon your allies, release the prisoners, feed my dog, water my plants, killthe king, check the mail, etc.).
Remember to ask permission to use this on your allies. Imposing a Charmed effect couldlead to problematic interactions within the party, but you will all benefit from havingeasy telepathic connections to each other.

Example Build – Mind Games
The Great Old One is not a combat subclass. This is not a hexblade seeking tostack big damage numbers or swing a magic sword. This is not The Fiend seekingto cast Fireball, then mop up survivors. The Great Old One offers more utilityoutside of combat, but very little that will help you survive fights. Instead,you should look to win fights before initiative is rolled.
Instead of a combat monster, we’re going to build a sneaky, deceitful Face that you can use to confuse and mislead other creatures, dominating social situations and sometimes mitigating combat situations by disrupting possible enemies before violence occurs. In combat we’ll need to fall back on core Warlock features, but outside of combat we’ll be terrifying.
Keep in mind that this build will require buy-in from your DM. If your DMisn’t inclined to let you telepathically convince guards to walk away or toconvince ogres to bicker amongst themselves, this build will be incrediblyfrustrating. At the same time, if your DM is willing to play along, try not toabuse things too much. If you can solve every problem by telepathicallyharassing other creatures, the game stops being a challenge pretty quickly.You should also strongly consider usingsafety tools.
Ability Scores
We’ll put our racial +2 into Charisma and our +1 into Dexterity. Basically standard for Warlocks. We don’t want to dump Wisdom because Insight will be helpful.
| Base | Increased | |
|---|---|---|
| Str | 8 | 8 |
| Dex | 15 | 16 |
| Con | 14 | 14 |
| Int | 8 | 8 |
| Wis | 10 | 10 |
| Cha | 15 | 17 |
Race
Kenku. We’re going to lean into tricky shenanigans, and being able to perfectly mimic sounds is thematically excellent and just a ton of fun to play with at the table. We also get two skills, which is fantastic. We’ll take Deception and Stealth.
Sadly, mimicry won’t work with our telepathy. According to Jeremy Crawford, you sound like yourself when speaking telepathically, but that doesn’t matter if your target has never heard your real voice because you exclusively speak via mimicry the rest of the time.
Background
Charlatan. Perfectly on theme. Deception will be redundant with our racialskill proficiency, so trade it for Insight since we can’t get that from ourclass. Sleight of Hand isn’t especially useful, so you might swap that forsomething like Perception.
You might see Forgery Kit on the list of proficiencies and think “redundant”,but double check the wording of the Kenku’s Expert Forgery trait. ExpertForgery gives you Advantage on checks, but doesn’t mention proficiency. Havingboth will make forgery very effective.
Regardless, you might trade one of the tool proficiencies for Thieves’ Tools if your party doesn’t have a Rogue. We’re going to have a lot of sneaky capabilities anyway, so filling in for a Rogue is on the table.
Skills and Tools
We’ll take Arcana and Intimidation from our Warlock skills. That gives usArcana, Deception, Insight, Intimidation, Sleight of Hand, and Stealth. Wealso get proficiency in Disguise Kits and in Forgery Kits.
We’re going to take Skill Expert at level 4, which will get us Proficiency inPersuasion plus Expertise in Deception.
Feats
At 4 we take Skill Expert. Proficiency in Persuasion, Expertise in Deception,+1 Charisma to stay on the Fundamental Math.
At 8 we take Telekinetic. It’s a great utility with no visible connectionbetween you and the effect, further adding to the tricky nonsense that we canaccomplish. It also gets us +1 Charisma.
At 12 we’ll take Guile of the Cloud Giant, offering a defensive Reaction andanother +1 Charisma to get us to 20.
At 16 and 19 we have open feat slots. Staples like Inspiring Leader and Luckywork great here.
Levels
| Level | Feat(s) and Features | Notes and Tactics |
|---|---|---|
| 1 | Otherworldly Patron: Great Old One Awakened Mind PactMagic Spells Known: – Dissonant Whispers – Hex CantripsKnown: – Eldritch Blast – Minor Illusion | For starting gear, take the light crossbow, an arcane focus, either pack, leather armor, and three daggers. With 16 Dexterity, a Light Crossbow is very briefly your best combat option. For the most part, we’re a very normal Warlock at this level. Awakened Mind is great for social situations where there’s a language barrier. That said, we can also use it for sneaky shenanigans. You can telepathically speak to any creature that you can see within 30 feet of you. This doesn’t require you to move or give yourself away, and telepathy doesn’t automatically give the target any idea who they’re hearing. Tell them that their shoe is untied. If you need to make a Deception check, consider hitting them with Hex to impose Disadvantage on Wisdom checks, which applies a -5 to Passive Insight. We’re taking Eldritch Blast and Hex because Eldritch Blast+Agonizing Blast+Hex is our go-to option in combat. It’s not super exciting, but it works well. |
| 2 | Eldritch Invocations – Agonizing Blast – Mask of ManyFaces New Spell Known: – Any | Agonizing Blast for the damage. Mask of Many Faces so that we canperform our telepathic shenanigans up close without arousingsuspicion. |
| 3 | Pact Boon: Pact of the Tome New Cantrips Known: –Friends – Guidance – Mind Sliver New Spell Known: –Invisibility | We’re leaning hard into utility and non-combat options, and Pact of the Tome is an amazing utility option. We only get cantrips from the basic Pact benefits, but the Invocations will give us ritual casting and other benefits. Invisibility lets us get into a place unnoticed, then start whispering forbidden truths to enemies before our friends kick in the door to capitalize on their disordered state of mind. |
| 4 | Feat: Skill Expert – Charisma 17 -> 18 – Proficiency:Perception – Expertise: Deception New Cantrip Known: –Any New Spell Known: – Suggestion | Proficiency in Perception gets us the last missing Face skill.Expertise in Deception lets us much more effectively mislead othercreatures by telepathically whispering to them.There are warm cookies in the kitchen. If you don’t eat them,someone else will eat them all before you get any. Suggestion overlaps with our sneaky whispering, butsometimes a Deception check isn’t enough to do the job. |
| 5 | New Invocation: – Book of Ancient Secrets New SpellKnown: – Enemies Abound Retrain Spell: – DissonantWhispers -> Hunger of Hadar | Welcome to the magical world ofRitual Casting! With no restriction on spell list, Book of Ancient Secrets makesthe Warlock the most effective ritual caster in the game. Startcollecting rituals immediately. You get two 1st-level rituals forfree. I recommend Comprehend Languages and Detect Magic. Bythis level our 1st-level spells from our subclass spell list lookineffective compared to higher-level spells, so now is a good time tostart retraining them. |
| 6 | Entropic Ward New Spell Known: – Hypnotic Pattern | Entropic Ward is the Great Old One’s best combat feature, but it’snot enough to win a fight for you. You may be tempted touse something other than Eldritch Blast with the free Advantage fromEntropic Ward. Fire Bolt sure looks tempting. But the DPR of thatsingle Fire Bolt with Advantage is worse than two shots from EldritchBlast+Agonizing Blast without advantage. Stick to EldritchBlast. |
| 7 | New Invocation: – Ghostly Gaze New Spell Known: –Summon Aberration | Awakened Mind requires you to see the target. Ghostly Gaze lets you see through walls. Together, you can see through walls and telepathically harass other creatures. I saw that. You should be ashamed of yourself. Summon Aberration feels thematically appropriate, and it’s also a very solid summon spell. |
| 8 | Feat: Telekinetic (Cha 18 -> 19) New Spell Known: – Evard’sBlack Tentacles | Yes, you can use Ghostly Gaze and Telekinetic at the same time. Yes,that means that you can effectively haunt things up to 30 feet awaywith a solid wall between you and your target. You can also do normalcombat things like moving enemies into area control effects. |
| 9 | New Invocation: – Gift of the Protectors New SpellKnown: – Telekinesis | Gift of the Protectors is like Relentless Endurance or Death Ward, but you get one use per long rest shared between every creature whose name you add to the page. Remember how we’re telekinetic? Now we’re extra super telekinetic. If moving an enemy 5 feet isn’t quite enough, bring up Telekinesis and start lifting your problems and putting them on high shelves where you can forget about them. |
| 10 | Thought Shield New Spell Known: – Synaptic Static | Thought Shield is spicy resistance to psychic damage. Go find a mind flayer to disagree with. Also, psychic fireball. |
| 11 | Mystic Arcanum: Mental Prison New Spell Known: – Any New Cantrip Known: – Any | No big changes here. |
| 12 | Feat: Guile of the Cloud Giant (Cha 19 -> 20) New Invocation: –Any | Max Charisma and add a cool new defensive option in combat. Thereare’t any must-have invocation options here. Maybe Repelling Blast togo with our shiny new third ray from Eldritch Blast. |
| 13 | Mystic Arcanum: Plane Shift New Spell Known: – Tasha’sHideous Laughter | Plane Shift to go meet your patron face to face for the first time.Regret your choices. Ask to crash on the couch for a Long Rest. PlaneShift home. Regret your life choices. We’re adding Tasha’sHideous Laughter at this level solely for use with Create Threall. Seebelow. |
| 14 | Create Thrall | You say “Thrall”, but I say “future mental spam call recipient”. Obvious recipients are your party for utility purposes, but any humanoid who you find who is incapacitated can become a thrall. It might never be useful, but maybe some time you’re trapped in a dungeon and need to call for reinforcements. Remember that the Charmed condition is not mind control. You get Advantage on Charisma checks to “interact socially” with the creature. This is great for social skills, and, between Advantage and Expertise, you can use Deception to convince your thralls of nearly anything. The dungeon outside of town is full of treasure. All you need is a picnic lunch and the Warlock’s 10-foot pole that they forgot. Pay special attention to the wording of the feature. Where Awakened Mind says “speak to“, Create Thrall says “communicate telepathically with“. I’m not totally certain, but this may mean that Awakened Mind is one-way, but Create Thrall is two-way. I haven’t found any discussion from WotC folks on the subject, so check with your DM. Because Create Thrall targets Incapacitated creatures, take a long look at your spell list and look for anything that makes targets Incapacitated, such as Tasha’s Hideous Laughter or Hypnotic Pattern. Unfortunately, Warlocks don’t get many options, but Tasha’s works for single creatures, while Hypnotic Pattern works for crowds. Raulothim’s Psychic Lance makes targets Incapacitated, but the spell’s duration ends at the beginning of your next turn, so the action economy doesn’t work unless you take two levels in Fighter for Action Surge. At this point, your life is all about creating thralls. If you see an opportunity, you take it. The more thralls you have, the better. |
| 15 | Mystic Arcanum: Glibness New Spell Known: – Any NewInvocation: – Shroud of Shadow | Cast Glibness. You have one hour to talk to all of your thralls and get 15 or better on the d20 roll. Time to turn your thralls into an army. Turn invisible. Walk around causing trouble both telepathically and telekinetically. |
| 16 | Feat: Any | – |
| 17 | Mystic Arcanum: Psychic Scream New Spell Known: – Any | Stunned makes the affected creature Incapacitated. Psychic Scream makes your targets Stunned. Create Thrall requires your target to be Incapacitated. Scream, then spend the next several turns high-fiving Stunned creatures to make them into Thralls. You have now turned a high-CR encounter into a collection of new friends. |
| 18 | New Invocation: – Visions of Distant Realms | My favorite scouting option, and, if you can get the eye around corners, you can use it with Awakened Mind to target them with spells or to telepathically speak to other creatures without spending Ghostly Gaze. |
| 19 | Feat: Any New Spell Known: – Any | It’s weird for level 19 to not change anything for us. Pick a coolfeat. |
| 20 | Eldritch Master | Literally always a disappointing capstone. |
