Star Spawn Vanguard

You are a warrior who foolishly delved into alien designs in hopes of acquiring strength or perhaps one who came in contact with some unearthly material. Either way, though you have managed to maintain your psyche, the corruption continues its work of altering your body.

Despite this, you persist, and against all odds you’ve discovered a way to use this corruption to your advantage in combat.

Manifest Maw

3rd-level Star Spawn Vanguard feature

Your mouth somehow becomes sinister and you gain a bite attack. If you hit with your bite you may reveal a mouth anywhere on your body to do so, as long as you have fewer mouths active than half your level in this class rounded up. This new mouth remains active for 1 minute. You may take this bite as a bonus action.

If you take at least an amount of damage equal to twice your level plus you constitution modifier at one time, the last mouth you revealed returns to inactivity. Your original mouth is not affected by this.

For every 2 mouths you have active, including your natural one, you gain +1 to your AC as the gnashing unnerves those who attack you.

Unsettling Whispers

3rd-level Star Spawn Vanguard feature

You can become a mouthpiece for your inner corruption. As a bonus action, you can begin to whisper things beyond your understanding. You may choose a number of targets within 30ft up to the number of active mouths you have and force them to roll a Wis save(DC =8 + proficiency + Con). On a failure they are frightened of you for 1 minute and they can redo the save at the end of each of their turns.

If you ever have fewer mouths active than creatures currently frightened by this feature, the effect ends on creatures of your choice until those numbers are equal.

This feature doesn’t affect deafened targets and it cannot be used if you are silenced.

You can use this feature a number of times equal to your Constitution modifier (a minimum of once). You regain all expended uses when you finish a long rest.

Rattling Scream

7th-level Star Spawn Vanguard feature

As an action, you can produce a scream so foul it shocks the system. You may choose a number of targets within 30ft up to the number of active mouths you have and force them to roll a Con save. On a failure they are knocked prone. If a creature is frightened of you and fails this save, they are stunned until the end of your next turn.

This feature doesn’t affect deafened targets and it cannot be used if you are silenced.

You can use this feature a number of times equal to your Constitution modifier(a minimum of once). You regain all expended uses when you finish a long rest.

Nauseating Bile

10th-level Star Spawn Vanguard feature

Your bites now deal 1d8 damage and count as magical for the purpose of overcoming resistance and immunity to nonmagical damage. Also, you have learned how to access some nauseating part of your anatomy. As an action, you can cause your mouths to vomit cosmic bile. Each mouth has a target within 30ft and mouths can share targets. Each target makes a single Dexterity save even if targeted by multiple mouths. On a failure, each target takes 1d6 acid damage per mouth targeting them and are poisoned for 1 minute . On a successful save, targets take half damage and aren’t poisoned.

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

Chilling Laughter

15th-level Star Spawn Vanguard feature

You have begun to embrace the futility of existence. As a reaction, when a creature makes an attack roll, ability check or saving throw, you may begin to laugh at them nihilistically. They must make a Charisma save. On a failure, they subtract a number equal to your number of active mouths from any attack roll, ability check, or saving throw they make until the start of your next turn.

This feature doesn’t affect deafened targets and it cannot be used if you are silenced.

You can use this feature a number of times equal to your Constitution modifier (a minimum of once). You regain all expended uses when you finish a long rest.

Land of Gnashing Teeth

18th-level Star Spawn Vanguard feature

Your bites now deal 1d10 damage.

Additionally, you can use an action to spread your corruption. For 1 minute, ground within 30 feet begins to turn doughy and mouths appear throughout it. This area moves with you and counts as difficult terrain for creatures of your choice, and all creatures in the area have disadvantage on your saving throws as the mouths on the ground mimic your own. While this feature is active you cannot be silenced unless it affects the entirety of this features area.

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