Otherworldly Patron: The Arcane Hive

The Arcane Hive.

Your patron is not a single being, but instead a mass of many unified entities that think and exist as one. At some point in your adventures, you have allowed a being like this into you, or had one enter against your will, and are now a part of their magical web of servants. These creatures are motivated by hunger, and consume the magical energy of those they live in.

Expanded Spell List.

The hive within you lets you choose from an expanded list of spells when you learn a warlock spell. The following spells are added to the warlock spell list for you.

Spell Level	Spells
1	Bane, Ray of Sickness
2	Animal Messenger, Web
3	Clairvoyance, Haste
4	Giant Insect, Locate Creature
5	Awaken, Insect Plague

 

Interwoven Swarm.

Starting at 1st level, your patron which dwells within you
begins to actively consume your magic, and responds to you
releasing it. When you cast a spell using a warlock spell slot,
you may choose to allow some of the swarm within you to
release for a short time. If you choose to do this, no action
required, choose a location within 5 feet of you for the swarm
to go as it leaves your body. If there is no open spaces within 5
feet of you, then the swarm is unable to release, and nothing
happens.
The swarm has the statistics of a Swarm of Insects, with
the following changes: It's hit points are instead equal to four
times the level of the spell cast to release it, it gains a bonus to
hit with attacks and to it's AC equal to the spell slot level used
to release it, it gains the ability to speak telepathically with you
regardless of what languages you know, and the damage it
deals is considered magical for the purposes of overcoming
resistances and immunities.
The swarm is simply that of minor drones, as the queen
would never risk its safety by leaving your body. The swarms
act on your initiative, but does not take it's turn unless you
command it to. You may command all of your released
swarms at once with a bonus action. Swarms stay released for
one minute, or until they are reduced to 0 hit points.

Hive Casting. 

Upon reaching your 6th level you gain the ability to channel
your magic through your swarms as you grow more magically
in tune with the hive that dwells within you. When you cast a
spell with a range of self, all of your swarms are also
considered to be under the effects that spell. Additionally,
when you cast a spell with a range of touch, you may deliver it
through a swarm as though it cast it.

Unified Protection. 

Once you have reached 10th level, your swarms gain the
ability to intervene with effects that would harm you when
they are nearby. When you would be hit by an attack and have
one of your swarms within 5 feet of you, you may choose to
use your reaction to have the swarm become the target of the
attack instead of you.

Magic Eater.

Upon reaching 14th level, you and your swarms become
imbued with the ability to eat magic that the hive that lives
within you uses to survive. When you or your swarm hit a
creature with a weapon attack, if that creature has any spell
slots, they must make a constitution saving throw against your
spellcasting DC. If they fail, they lose their lowest level
unexpended spell slot as if it had been expended.
In addition to this, if you have at least two swarms released,
you may use your action to cast the spell dispel magic without
expending a spell slot.
