The World Eater (Patron: Polukranos)

Your patron is Polukranos, the World Eater—an ancient and monstrous Hydra Titan from Theros, the embodiment of nature's wrath and unrelenting hunger. Your pact is not one of conversation or bargain, but of instinct, survival, and violent growth. Polukranos does not speak. It only hungers. Through your bond, you channel primal fury, regenerating strength, and untamable pursuit.

You stalk prey, overwhelm with sudden violence, and endure punishment that would break others. Your magic manifests as venom, bone, and the primal echoes of a predator too vast for mortal comprehension.

Predatory Boon

When you reduce a creature to 0 HP, you gain temporary hit points equal to your warlock level + your Charisma modifier.

Additionally, when you cast a spell that deals damage, you can choose for it to deal piercing or poison damage instead of its normal type, representing Polukranos’s venom-laced strike.

Hydra’s Resilience

You gain the ability to rapidly regenerate, like a severed hydra head reborn.

When you take damage that would reduce you to 0 HP, you can use your reaction to instead drop to 1 HP, and immediately gain resistance to all damage until the end of your next turn.

You can use this feature once per long rest, or by expending a Warlock spell slot to use it again.

Relentless Pursuit

You gain Blindsight 10 ft., and you cannot be hidden from by non-magical means.

Additionally, when a creature within 30 feet of you attempts to disengage, teleport, or flee, you can use your reaction to immediately move up to your speed toward that creature without provoking opportunity attacks.

Avatar of Hunger

As a bonus action, you can enter a predatory Avatar State for 1 minute. For the duration:

- You gain advantage on all melee and ranged spell attacks.
- Once per turn when you deal damage with a spell, you can target an additional creature within 10 feet of the original target.
- When you reduce a creature to 0 hit points, you can make one melee spell attack or cast Eldritch Blast as a free action.

Once you use this feature, you can't use it again until you finish a long rest. When the effect ends, you suffer one level of exhaustion unless you finish a short or long rest first.
