## Warlock Patron

### {subclass-name}
An ordinary rat colony is usually a few individuals; a large one can contain a dozen or more. A ratmind colony contains *thousands*, so many that the rats find themselves welded into a psionic hivemind. Scholars disagree on whether ratminds arise spontaneously or whether the rats need a specific psionic awakening; extraplanar explorers even report rats with exposed brains, naturally forming mighty ratminds.

Regardless, a powerful ratmind develops psionic powers great enough that it can support even a powerful warlock. Ratmind warlocks gain a share of their patron's psionics, acquiring psionic powers and a limited ability to connect minds themselves. These warlocks also tend to take on the ratty attributes of their patrons; many have a furtive, scurrying demeanor.

#### Expanded Spell List
The {subclass-name} 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.

| Warlock Level  |  Spells |
|:---:|:-----------|
| 1st  | *future insight^K^*, *unlocked potential^K^* |
| 3rd  | *glimpse the future^K^*, *levitate*  |
| 5th  | *nondetection*, *deepen shadows^S^* |
| 7th  | *confusion*, *phantasmal killer* |
| 9th  | *shockwave^K^*, *psychokinesis^SDS^*  |
<small>The following swaps will improve your experience: replace *confusion* with *bewilder^SDS^*, and *phantamsal killer* with *phantasmal horror^SDS^*.</small>

> Spells marked with ^S^ were created by [somanyrobots](https://www.gmbinder.com/share/-NMZq9u_rDyV_XD5YTxf "So Many Spells)"). Spells marked with ^SDS^ were created as part of the [Spells That Don't Suck](https://www.gmbinder.com/share/-NR0OWlW60yv2EfA3qQp "Spells That Don't Suck") project. Spells marked with ^K^ were created by [KibblesTasty](https://www.kthomebrew.com/s/SpellCompendium-v20_CC.pdf "Kibbles' Casting Compendium") and used with permission. All are linked in the Spell Sources appendix.

#### Psionic Link
At 1st level, you gain a psychic connection to your patron, and the ability to psychically connect to other creatures around you. When you finish a long rest, you can perform a special ritual over 1 minute to establish a telepathic bond with a number of willing creatures within 30 feet up to your proficiency bonus. Every creature within the bond can communicate telepathically with every other one, as long as they are within 30 feet of each other.

You can end your Psionic Link as an action, and it ends automatically when you finish a long rest.

\pagebreakNum

#### Projected Vermin
Also at 1st level, you gain the ability to create a psionic projection of a rat. As a bonus action, you can conjure a Tiny psionic rat ghost in an unoccupied space within 30 feet of you. This psi ghost has the statistics of a rat, and you interact with it following all the rules as if you summoned it with *find familiar*. This rat is obviously spectral in nature to anyone who observes it.

When you cast a spell from your Expanded Spell List, you can cast it as if you occupy the rat ghost's space. If you do so, the rat ghost dies. If you create a new rat ghost, any existing rat ghost dies.

#### Scurry and Scuttle
At 6th level, you gain some of the rat's hardiness and ability to sense danger. You gain resistance to poison damage and advantage on saving throws against the poisoned condition. In addition, you now have advantage on passive Perception checks, and you automatically Dash (no action required) on the first round of combat.

> It's a little buried in the rules, but advantage on a passive check results in a +5 bonus.

#### Multiplicative Mind
Also at 6th level, your Psionic Link allows you to increase your arcane might in the same manner as your patron's networked mind. When you establish your Psionic Link, you gain a number of additional spell slots. You can choose how many spell slots and of what levels, but their combined levels can't be greater than the number of creatures in your Link.

These spell slots can't be at a higher level than the spell slots from your Pact Magic feature. These spell slots fade if unused when you finish a long rest.

#### Rat Swarm
At 10th level, when you create your Projected Vermin, you can choose instead to create a Small or Medium swarm of psionic rat ghosts. This uses the statistics of a swarm of rats, but uses your spell attack modifier to hit with its attacks. It can't use its own action to attack, but you can use your bonus action to command it to take the Attack action. If you create a new creature (either a swarm or a single rat ghost), any existing rat ghosts die.

When you cast a spell from your Expanded Spell List, you can cast it as if you occupy the swarm's space. If you do so, the swarm loses 5 hit points, but its next attack has advantage and deals 2d6 extra psychic damage.

#### Hive Mind
At 14th level, you can expand your mind by drawing on the creatures around you, following in your patron's tiny footsteps. When you cast a spell while your Psionic Link is in effect, you can choose to eject any number of creatures from the Link. If you do so, you gain a bonus to the spell attack roll or save DC equal to the number of creatures removed.
