The Brood

The Brood, an eldritch abomination from the Shadowfell, an ever-growing mass of souls connected together into an endlessly hungry, growing amalgamation. It increases in power by the second, its influence steadily spreading to the material plane as more dying souls converge into its being... and one can only wonder how long it will be until it arrives itself.

Manifest Soul

1st Level Brood Feature

The brood assimilates and links together souls - including yours. As an action on your turn, you may summon one of these assimilated souls within 5 ft. of you. This soul takes on your appearance, but looks vengeful and forlorn, and certain elements of it looks incorrect, retaining minor elements from it's previous life. The stat block for this spirit is visible here: https://i.imgur.com/ilttIk1.jpeg . After a minute, the soul disappears. 

In combat, the Soul 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. As a bonus action, you may command all of your summoned souls to use the 'Spiteful Blast' attack, choosing each target individually on their turn. You may also use your Bonus Action to command one of your souls to use an action other than dodge, such as casting a spell. If you are incapacitated, any Souls that you have currently summoned disappear.

This Souls disappear if they are no longer on the same plane of existence as you, or if they end their turn in an extradimensional space (such as a bag of holding, portable hole, etc.) that you are not also inside of.  

At level 1, the maximum amount of souls you can have summoned is 1. This increases to 2 at level 5, 3 at level 11, 4 at level 17, and 5 at level 20.

Infuse Souls

6th-Level Brood Feature

Starting at 6th level, when you summon a soul with the 'Manifest Soul' feature, you may infuse a summoned soul with a spell. While summoning a Soul, cast a spell using either your Pact Slots or a cantrip, using all required components. The spell does not immediately take effect - instead, the soul can cast it once without requiring any spell slots or components (If you infuse a cantrip, it may cast it multiple times). As an action, you may also infuse an additional spell into a Soul that is already summoned, following the same rules as listed above.

Whenever a Manifested Soul casts a spell, they use their summoner's Spell Save DC, Spell Attack Modifier, and Spellcasting Ability (for the purposes of Dispel Magic/Counterspell). It is cast at the same level that the spell was originally cast at. 

If you fail a concentration saving throw any of your souls are concentrating on a spell, all of your souls drop their concentration.

At the end of each of your turns, if any of your souls are concentrating on a spell, make a Concentration Saving Throw: DC 10 + 4^(the number of spirits concentrating on spells), regardless of whether you yourself are concentrating on a spell or not.

Brood Flood

10th Level Brood Feature

Starting at Level 10, the Brood allows you to unleash it's power as a torrential flood, instead of the small drips you have been opening so far. When you use an action to summon a Soul using Manifest Soul, you may manifest extra souls equal to half of your proficiency bonus (rounded down). When you do this, all of your summoned creatures, and creatures summoned by your souls, gain advantage on attacks until the end of the turn.

You may only use this feature once per short or long rest. 

Soul Capture

14th Level Brood Feature

Starting at 14th level, you have mastered the art of quickly assimilating souls into the Brood. As a reaction, when a creature (that is not a Manifested Soul, or a temporary creature summoned through the use of a spell) within 60 ft. of you dies; you may immediately summon a Manifested Soul within 5 ft. of where they died. This Soul lasts for 12 seconds, and does not count towards the limit of how many souls you can have. As well, if the creature that died had the either Spellcasting, Pact Magic or Inherent Spellcasting features, you may choose one spell of 5th level or lower that dead creature had the ability to cast - the Manifested Soul gains the ability to cast that spell once.
