The King of Mages

The abyss of magic is steep and unforgiving. Warlocks under the patronage of Mawgolos the King of Mages know this better than any, for he is an uncaring and awful silhuette seen in the farthest reaches of the far realm. Mawgolos's unending stream of power fills his charges to the brim and beyond. Unwitting warlocks who stumble upon this old god without preparation cease to be shortly after, as their thirst for power quickly drowns them in a magnificent explosion of blue light.

Elder God of Magic

There is no way to form a direct patronage with Mawgolos, his power is so great that even a shred of the smallest amount of power giveable is far beyond mortal understanding and capabilities. One can however, funnel it through a grim buffer of sorts. By tricking an unwitting warlock into directly making a pact with Mawgolos, one can seal the soul of the pact maker (before they explode) into a tome and use it to channel Mawgolos.

The consequences of this are immense as only an evil being would sacrifice another and trap their soul for eternity. The power gained in return is greater.

While a warlock does not need to craft the book themselves in order to make it, reading the book is considered taboo, as it opens the soul to the infinite knowledge of the King of Mages, and almost always corrupts the mind beyond salvation.

Greater Power of an Elder God

Patronage to Mawgolos, the great elder god of magic, grants warlocks greater power than they can concieve. Their tome is filled with unending power and knowledge, locked behind the danger of insanity.

Warlocks of this patron gain an extended spell list almost akin to a wizard's grimoire. Gaining spells from the wizard's spell list of the same level. Changing spells comes at a DC 15 Wisdom saving throw and cannot be done in combat.

Seize Magic

Starting at the 1st level, warlocks of Mawgolos gain the ability to pull magic out of the air, literally! Once per day you may pull 1 Essence of Mana from the void into the material plane. These small blue crystals can be used to restore one spell slot of any level and naturally dissolve back to the aether at a rate of {Total crystals owned/2} every five days. Alternatively a warlock of Mawgolos can sacrifice an Essence of Mana to their Tome of Magic to halt the deterioration of all other crystals in their possession for one day.

Essence of Mana can also be obtained by casting Dispel Magic. When Dispel Magic is successfully cast on a spell, a single crystal drops no matter the level of the original spell. Dipel Magic is cast at will with no cost, similar to a cantrip.

Dispel Magic can now be cast on grappled or unconscious creatures. When successfully cast the warlock gains all the spell slots the creature has remaining at the level of which Dispel Magic was cast or lower in the form of Essence of Mana crystals. Grappled creatures must succeed a wisdom saving throw against your Spell save DC or lose the spell slots described. Unconscious creatures automatically fail the wisdom saving throw.


Summon Mana Familiar

Beginning at the 5th level, you gain the ability to summon a familiar by combining Essence crystals. Increasing the amount of crystals used increases the familiar's functionality, while keeping all abilities of previous levels.

Mana Familiars
Crystals Used Form Function
1 Cephalopod dim light 10 ft radius
2 Songbird Shared senses
3 Serpent +2 to grapple checks
4 Mana Wyrm Interact with objects 10 lbs
5 Mana Dragon Channel cantrip 200 ft

Each familiar is considered a

construct and behaves in a

certain way. The cephalopod

familiar does not understand

commands and will only float

near the warlock who

summoned it. The songbird

PART 1 | MAWGOLOS

the warlock that summoned it, maintain shared senses between realms, and can be controlled directly when the warlock meditates or is unconscious except during rests.

The serpent is worn by you or your ally, it provides the wearer with a +2 to any grapple checks against a creature the same size or lower as the wearer.

The Mana Wyrm is a miniature 2 legged wyrm that floats about in any manner the warlock sees fit. It has a controllable range of 200 ft, beyond that the warlock must take control by entering a trance-like state. The Mana Wyrm Shares INT, CHA, and DEX stats with the warlock who summoned it and can interact with the world up to 10 lbs. In other words if the interaction would exceed 10 lbs, the Mana Wyrm cannot interact with it. Mana Wyrm has an AC of 10+DEX, a STR of 3, and a WIS of 13 unless controlled by the warlock.

The Mana Dragon is a small sized proportional ethereal dragon which behaves in a similar manner as the Mana Wyrm with the same range. The Mana Dragon, however, can channel the warlock's cantrips up to 200 ft. Beyond 200 ft the Mana Dragon can be controlled by entering a trance-like state.

Additionally the mana familiars can be dispelled at any time to refund the Essence crystals used in their construction.

Mana Tap

At the 9th level you begin to feel a connection to mana in all its forms, seeing little difference between "free" mana in the air and mana "trapped" within the confines of other creatures. You now have advantage on all Dispel Magic casts. Additionally You gain a unique spell Siphoning Beam.

Siphoning Beam

5th-level abjuration


  • Casting Time: 1 action
  • Range: 60 feet
  • Components: M, S (Essence of Mana crystal)
  • Duration: concentration

You outstretch your hand and sacrifice one of your Essence crystals as a catalyst to begin drawing energy from a living creature. The spell must be channelled for at least three turns and the creature makes a wisdom saving throw against your DC spell save + any buffs to die rolls each turn.

If the creature succeeds on any saving throws the spell ends. For every failed saving throw the the following save has disadvantage. The disadvantage does not stack.

On the first two failed saves you gain Essence of Mana crystals equal to the creature's total health/20 (round up). On each subsequent failed save the creature takes 1d6+Spell attack modifier to constitution.

Sacrifice to the Void

Your tome has unveiled secret rituals to you. At the 14th level the secrets to one of these rituals has become very clear. 3 times per Long rest you can use a bonus action in combat to mark a target. If that target dies before your next turn you gain all the Essence crystals that target would be worth. If the target has no spell slots it is worth its max health/20 (round up) crystals. If the target has spell slots it is worth the total number of spell slots remaining ignoring spell slot level.


Avatar of an Old God

Other patrons are weak. By comparison so are their warlocks. Upon reaching mastery of their class most warlocks can do little more than entreat their masters for a few more grasps at feeble magics. You can do so much more.

While Mawgolos's power is far beyond the understanding of mortal men, so are you. At the 20th level you have managed to attune yourself with Mawgolos himself and can now channel his power directly for up to 10 min. per long rest. You have also discovered three unique ways to channel the raw magics of the ancient one.

Avatar of Mawgolos - perhaps the simplest and deadliest of the three, you become an incarnation of your god for 10 min. During that time you no longer need spell slots to cast spells, additionally your Spell attack modifier - your proficiency bonus + your Charisma modifier + your Wisdom modifier + your Intelligence modifier. All spell effects activated while in this state are ended when exiting.

Celestial Body - Inspired by your familiars, who are impenetrable until their damage threshold is reached, you have discovered a way to cloak yourself in that same energy. the drawback is that this mana construct is far too large to move autonomously and must be piloted from within. Additionally this form costs 20 Essence crystals to manifest which are refunded if the Celestial Body is dispelled, but lost if the Celestial Body is destroyed. In this form you are considered a Gargantuan size and automatically succeed grapple checks against creatures Large through Small, with disadvantage on creatures smaller. Creatures that are automatically grappled can be held in one hand and Siphoning Beam can be cast on them instantaniously at no cost. The creature automatically fails 4 saving throws. The body itself replaces the following stats

  • 400 hit points
  • AC of 12
  • STR of 30

Horrific Genocide - Expanding on the dark ritual from before, you've added your own twist to the mana generating sacrifice. When targetting a creature with this spell you forcefully extract the essence of that creature to use as a magical resonator. After one minute of channelling, all creatures of the same race within one mile are executed and you gain Total Health of all creatures/10 (minimum one per creature) Essence of Mana crystals.
