Otherworldly Patron

The Blood Moon

Your patron is an unholy entity present only on the most dangerous nights, when the sky is stained red by the moon's glowing crimson visage. On such nights, people are known to act strangely; fearsome creatures are known to arise, and people are advised to lock their doors with the strongest of protections. At this time, some say one can trade with it; some say, with the right offering, one may be given what they seek—but always at a price. Your pact with the Blood Moon grants great power, but at the cost of your life force, and perhaps even your empathy and morality.

Moonspeaker

At 1st level, your connection to the blood moon allows you to always know the current phase of the moon, as well as predict the phase of the moon on a future date.

Invigoration

At 1st level, you can tap into the blood moon's supernatural vigor. You have a pool of d6s equal to your Charisma modifier (min. 1). You can use an action to roll any number of these dice and gain temporary hit points equal to the total rolled + your Charisma modifier, for 1 minute.

After consuming a die with this feature, you cannot roll it again. This feature resets at the end of a long rest.

Moonlit Ceremony

At 6th level, your maximum number of Invigoration dice is increased by one.

Also, when you or a creature within 30 feet of you are reduced to 0 hit points but are not killed outright, you can use your reaction to expend an Invigoration die. The chosen creature regains hit points equal to the amount rolled + 1.

Once you use this feature, you cannot use it again until you finish a long rest.

Seek the Blooded

At 10th level, your maximum number of Invigoration dice is increased by one. They become d8s.

Also, you become anointed in your patron's unnatural light, gaining resistance to radiant damage. Also, you gain darkvision of 60 feet if you do not already have darkvision, and you can see through magical darkness.

Call of the Red Night

At 14th level, your maximum number of Invigoration dice is increased by one.

Also at 14th level, you can call the blood moon to manifest in the sky. Choose one location within 1,000 feet that you can see that has open sky. As an action, you can expend 3d6 hit points to call the blood moon's dim red glow to flood a 45-foot radius area for 1 minute, reducing the light level of the area to dim light. All creatures (except you) in the area who can see the sky must make a Wisdom saving throw or be frightened, and attempt to flee from the area. They must repeat the saving throw at the beginning of each of their turns until the duration expires, regardless of whether they failed the first saving throw.

During this time, any Invigoration die you roll is treated as its maximum number.

This feature resets at the end of a long rest.

Eldritch Invocations

Bloodedge

Prerequisites: Blood Moon patron, Pact of the Blade

You can conjure a weapon imbued with vile moonlight, the Bloodedge. The Bloodedge takes the form of any weapon that deals slashing damage. When you manifest Bloodedge, you sacrifice 1d6 hit points. Every successful hit with the weapon for 1 hour deals 1d4 additional necrotic damage.

Cloak of the Long Night

Prerequisites: Blood Moon patron, Pact of the Cloak

Your cloak magnifies the power of the moon. When you roll an Invigoration die, you can reroll each 1 once. When you reach 10th level, you reroll each 1 or 2 once.

Death Sense

Prerequisites: Blood Moon patron, 5th level

You can cast bloodsight at will, without expending a spell slot. However, you must still expend hit points, as normal.

Eviscerate

Prerequisites: Blood Moon patron, eldritch blast cantrip

When you hit a creature with eldritch blast, you can cast bloodburn as a bonus action using a warlock spell slot.

Life Link

Prerequisites: Blood Moon patron, Pact of the Chain

You can borrow the life force of your familiar as an extension of your own. When you lose hit points with your familiar within 30 feet of you, you can choose for your familiar to take the damage, instead. You take any excess damage if your familiar is reduced to 0 hit points.

The Red Codex

Prerequisites: Blood Moon patron, Pact of the Tome

Choose any two 1st-level spells with the hemomancy tag. They are added to the warlock spell list for you. When you gain a warlock level, you can exchange either or both of these spells for any other spell with the hemomancy tag, as long as they are of a level you can cast.

Waxing Favor

Prerequisites: Blood Moon patron

When you cast a spell with the hemomancy tag (or use Call of the Red Night), you mitigate some of the damage, a number of hit points equal to your Charisma modifier.
