The Chained One

A being of immeasurable power, bound by chains and sealed away for eternity. However, its influence over mortals hasn't waned. It calls to those who feel they are chained; by rules, by laws, and even literal chains. It teaches them to break their chains, to become the master instead of the slave. Inevitably, it seeks to be released, and unleash its vengeance upon those who bound it many eons ago.

Chained Servant

Starting at 1st level, you gain the Find Familiar spell and can cast it at will without needing material components. The spell doesn't count against the number of spells known and follows the specifics listed under Pact of the Chain.

If you later choose Pact of the Chain, your familiars become more potent. You can summon a beast, fiend, or fey with a CR equal to half your Warlock level (rounded down).

Servant's Shield

Starting at 6th level, your familiar can take damage meant for you. As a reaction when you take damage from an attack or spell, and if your familiar is within 60 ft. of you, it takes half the damage. (This feature doesn't work if both you and your familiar are affected by an AoE spell).

Servant's Bond

Starting at 10th level, an invisible link connects you to your familiar. Any spell you cast with a range of Self also targets your familiar. Additionally, whenever you cast a spell that requires concentration, your familiar can make the concentration checks instead of you.

Chained Oblivion

Starting at 14th level, you can bind other creatures to your service. As an action, choose one creature you can see within 60 ft. of you. That creature must succeed on a Charisma saving throw versus your Warlock spell DC or become chained to your service. For the next hour, it must obey your commands to the best of its ability.

Once you have used this feature, you can't use it again until you finish a long rest.
