The Binder Patron

The Binder is an otherworldly patron who is invested in the contract that was created with the warlock. To help ensure their investment meets the end of their contact, they bind a monstrosity to guard and more directly monitor the warlock. The Binder can be a number of things, from a demon lords, pit-fiends, ancient aberrations,  archfey, archangels, primordials, wyrms, or even someone who was once mortal and achieved a status close to godliness. 

One thing is certain from the warlock the Binder create pacts with, it is to serve a higher purpose and plan that only the patron is aware of and is going to ensure comes to fruition.

Bound Monstrosity

Your contract has granted you an unnatural guardian, a bound monstrosity. It's friendly to you and your companions, and it obeys your commands. See its game statistics in the Bound Monstrosity stat block, which uses your proficiency bonus (PB) in several places. You determine the creature's appearance and whether it has two legs or more; your choice has no effect on its game statistics.

In combat, the monstrosity shares your initiative count, but it takes its turn immediately after yours. It can move and use its reaction on its own, but the only action it takes on its turn is the Dodge action, unless you take a bonus action on your turn to command it to take another action. That action can be one in its stat block or some other action. If you are incapacitated, the monstrosity can take any action of its choice, not just Dodge.

You can cast spells with the range of Touch though the bound monstrosity if it's within 120 feet of you. You can also cast spells that has the range of Self targeting yourself or the monstrosity within the same range. The bound monstrosity's slam attack counts as a melee weapon worth at least 1 sp for the purpose of required spell casting components.

While the bound monstrosity is technically around at all times, as an Action, you can temporarily dismiss the monstrosity. As an Action while it is temporarily dismissed, you can cause it to reappear in any unoccupied space within 30 feet of you.

If it has died, you can expend a Warlock spell slot. The bound monstrosity returns to life after 1 minute with all its hit points restored.

At the end of a long rest, you can create a new bound monstrosity to regain all its hitpoints. If you already have a monstrosity from this feature, the first one immediately vanishes and comes back at full hit points. The monstrosity also perishes if you die.

Soul Bound Synergy

Starting at the 6th level, your patron has granted you power to be more synchronized with the bound monstrosity.

You Bound Monstrosity gains the following Reaction: 

• Deflect Attack. The monstrosity imposes disadvantage on the attack roll of one creature it can see that is within 5 feet of it, provided the attack roll is against a creature other than the monstrosity.

Additionally, when the bound monstrosity successfully hits a target with Slam, you can use your reaction to make an attack of opportunity against the target with a melee attack, ranged attack, or cast any cantrips other than Eldritch Blast once per short or long rest.

Rebound Vigor

Starting at the 10th level, when you cast a warlock spell, you can gain Temp Hit Points equal to half your warlock level (rounded down) + your Charisma modifier for you or the bound monstrosity if it's within 30ft.

Calamitous Arrival

When you reach 14th level, you've learned how to call the bound monstrosity in an overwhelming assault when you cast a spell. You are able to cast a warlock spell on a target or within a location with doubled proficiency for its spell hit or spell DC that will summon your bound monstrosity to or within that location with full Hit Points. Following your turn, the bound monstrosity can use an action to attack with advantage or take the dodge action. 

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