Comments from the Knuckle: This patron came about when someone on the Giant in the Playground forums asked what a Warlock bound to the Tarrasque would look like. Five minutes later, I presented the first draft of the patron below. Each of the features is inspired by a feature possessed by the Tarrasque. With that said, please enjoy my first contribution to Middle Finger of Vecna, Otherwordly Patron: the World-Eater! If you have any questions, comments, or concerns, feel free to drop them in the comments section below, and I will answer! :)
Few warlocks follow the breadcrumbs of ancient, cryptic riddles that detail how to forge a pact with the World-Eater. This titan goes by many names: the King of Monsters, the Bottomless Hunger, the Great Maw; but its true name is the Tarrasque, a legendary creature of untold power. Without question, it is the most powerful creature on the Material Plane, curbed only by its own dormant slumber, to which it returns for decades or centuries between waking fits of destructive rage.
This single creature can decimate kingdoms and bring empires to their knees, and it does not give its power easily. It is said that the ritual to gain the World-Eater's patronage subtly manipulates the dormant titan's dreams, bringing the prospective warlock into its favor. Performing this ritual is perilous, however; agitating the tarrasque while it slumbers may cause it to awaken, once again visiting its legendary destruction on the world.
Expanded Spell List
Your pact with the World-Eater allows you to choose from an expanded list of spells when you learn a new spell. The following spells are added to the warlock spell list for you.
World-Eater Expanded Spells
|1st||absorb elements, earth tremor|
|2nd||alter self, enlarge/reduce|
|4th||death ward, freedom of movement|
|5th||destructive wave, planar binding|
Starting at 1st level, you have been empowered by your patron in such a way that none may doubt your connection to the tarrasque. You can now target objects and structures when you cast eldritch blast. Whenever you cast eldritch blast or make a melee attack against an object or structure, you deal double damage. This also applies to creatures of the “construct” type.
Starting at 6th level, you can use your action to gain resistance to damage dealt by spells and other magical effects. Your resistance lasts for 1 minute.
Once you use this ability, you can't use it again until you finish a long rest.
Starting at 10th level, your patron's presence has taught you to be fearless and your presence is nothing short of terrifying. You are immune to being frightened, and when another creature attempts to frighten you, you can use your reaction to frighten them. The creature must succeed on a Wisdom saving throw against your Warlock spell save DC or be frightened by you for 1 minute.
Once you use this ability, you can't use it again until you finish a short or long rest.
Starting at 14th level, when you are targeted by a magic missile spell, a line spell, or a spell that requires a ranged attack roll, you can use your reaction to roll a d6. On a roll of 1-4 the effects of the spell occur as normal. On a roll of 5, you are unaffected. On a roll of 6, you are unaffected, and the effect is reflected back at the caster as though it originated from you, turning the caster into the target.
