The Monster

Warlocks who enter a pact with The Monster gain the terrifying ability to transform into monstrous beings, embodying the raw, untamed power of their inner monster. These warlocks can shift their form to gain the strengths and abilities of fearsome creatures, from enhanced physical prowess to supernatural resilience. This transformation reflects the chaotic nature of their patron, allowing them to unleash havoc upon their foes while teetering on the edge of losing their humanity. Bound by a pact that channels dark magic into primal fury, these warlocks must navigate the thin line between power and monstrosity.

Transformation

1st-level Monster feature

You manifest an aspect of your patron’s dreadful power, embracing a grotesque form that reveals the monstrous nature lurking within all beings. As a bonus action, you transform for 1 hour, invoking a horrifying change in your appearance. You gain the following benefits while transformed:

• You gain temporary hit points equal to 1d10 + your warlock level. If you kill a creature whilst in this form you gain temporary hit points equal to 1d10 + your warlock level.
• Choose one of the following movement adaptations:
  •  Burrowing: You gain a burrow speed equal to your walking speed.
  •  Climbing: You gain a climb speed equal to your walking speed and can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.
  •  Swimming: You gain a swim speed equal to your walking speed and can breathe underwater.
• Your limbs twist and elongate, sprouting claws, fangs, or other natural weapons. These natural weapons deal 1d8 + your Charisma modifier as slashing, piercing, or bludgeoning damage (your choice), and count as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage. You have a +1 bonus to attack and damage rolls made with these natural weapons.

You can transform a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.

The appearance of your Transformation is a horrifying reflection of your inner fears, regrets, and doubts about yourself. Your skin may crawl with writhing tendrils, your eyes may bulge unnaturally, or your mouth may stretch into a ghastly grin filled with too many teeth. This transformation is a visceral reminder of the dark pact that binds you, it is painful and terrifying to behold.
