Titan Patron (Cha)

Your patron is a being of unfathomable size, age, and strength, such as an astral dreadnought, an empyrean, a kraken like Slarkrethel, or a tarrasque. Titans are primal beings born of great powers akin to the divine but unfettered by the bonds of faith. Due to their immense strength and uninhibited nature many titans are pursued and bound by great collective efforts of societies or imprisoned by rival powers. A titan who seeks a pact with a warlock is usually one who desires escape from its imprisonment, most often to take vengeance on its captor. However, captivity and solitude may instead cause madness to bloom in the titan, who may seek escape so that it can consume all of existence. In exchange for the breaking of its chains, the titan grants the warlock increased size and strength, often accompanied by its horrible hunger.

Gigantic

At 1st level, your patron grants you greater size and strength. If you are Medium or smaller, your size permanently increases by one category, multiplying your weight by 8. You choose how your dimensions alter to accommodate your new size and weight. When you gain this feature, your equipment and anything you’re wearing or carrying grows to match your new size, but their statistics and value are otherwise unchanged. Each magic item you attune to also grows to accommodate your new size, where applicable, and returns to its normal size if you break your attunement with it. Additionally, you can choose to use Strength, instead of Charisma, as your warlock spellcasting ability. If you choose to use Strength, all warlock features and Eldritch Invocations that reference your Charisma modifier use your Strength modifier instead. You must make this choice when you gain this feature.

Great Hunger

                 Starting at 1st level, your appetite, like your patron’s, becomes nigh impossible to satisfy. Your stomach becomes a portal to a demiplane, in which you can store objects. As an action, you can devour an object that is at least 1 size smaller than and store it in the demiplane, or regurgitate an object stored within the demiplane. The objects in your demiplane must have a combined weight in pounds equal to you carry capacity, these objects do not count towards your carry weight. If you attempt to store an object that would push the total weight beyond this number, you immediately regurgitate it and take 1d8 necrotic damage, which can’t be reduced or prevented in any way.
                The objects within your demiplane can’t be accessed or detected by other creatures except through means that would allow them to access or view other planes, such as the gate spell.
               When you die, you regurgitate everything stored within your demiplane

Wrath of the Titan

Starting at 6th level, once per turn when you hit a creature
with a melee attack, you can draw on your patron’s strength
and mass to cause the attack to deal an additional 2d6 force
damage.
This force damage increases to 3d6 when you reach 10th
level in this class, and to 4d6 when you reach 14th level in
this class.

Titan Spell

The Titan lets you choose from an expanded list of spells when you learn a warlock spell. The following spells are added to the warlock spell list for you.

1st absorb elements, earth tremor
2nd enhance ability, enlarge/reduce
3rd erupting earth, slow
4th gravity sinkhole, stoneskin
5th destructive wave, maelstorm

Colossal

At 10th level, your patron gifts you a portion of its incredible resilience. Your hit point maximum increases by 20, and increases by 2 whenever you gain a level in this class. Additionally, whenever you would take damage, you can use your reaction to reduce the damage by half your warlock level.

Swallow Whole

Starting at 14th level, you can attempt to swallow a creature within 5 feet of you that is your size or smaller.

When you strike a hostile creature you may force that creature to make a contested grapple check or be swallowed into your demiplane. The creature’s weight doesn’t count against the maximum weight that can be stored within your demiplane. While a hostile creature is trapped within your demiplane your speed is reduced by half, your AC increases equal to your Con modifier. At the beginning of your next turn, or if you fall unconscious or die, you regurgitate the creature prone into the nearest unoccupied space within 5ft of you. If the creature would die as a result of the strike you may roll up to 4 hit die and gain temp hp equal to the roll.

Alternatively as a reaction you may swallow an allied creature, when you do so you suspend all negative effects on the target. If this reaction would swallow an ally that is the target of an attack or spell negate those actions on the swallowed ally. At the beginning of their next turn you regurgitate the ally into an unoccupied space within 5ft of you, when you do, you and the ally may roll up to 4 hit die divided as you choose between the two of you. You both gain temp hp equal to the dice rolled.

Once you use this feature, you can’t use it again until you finish a short or long rest.
