Starting at 1st level, You find your pain is best relieved when other's know the feeling of it, with a hypnotic tinge in your mind, you push the horrific feeling of writhing, clawing, hatching into whatever poor soul you choose.  As an action, you can choose an amount of creatures equal to your charisma modifier that you can see within 30ft of you, they must make a wisdom saving throw or suffer the frightened condition and fall prone. This effect lasts up to one minute, at the start of their turn they can make an additional saving throw to end the effect.

Visceral Attack

Starting at 6th level, You let the horrid partnership you harness leak into your physical form for an inkling of time, falling into complete insanity to it's tendencies in order to will a slight bit of it's form. As a bonus action you can activate this ability at your own expense, make a wisdom saving throw, you gain the following effect on a successful save.

• You add 2d12 damage to your next weapon attack or damaging spell.

On a failed save the ability, the effect still occurs but with this drawbacks.

• Enemies have advantage on attack rolls against you and you are unable to take reactions until the start of your next turn.

Symbiotic Balance

Starting at 10th level, It seems like the foul concept once festering with in you is beginning to slow, maybe it's nesting? more likely you've gone numb to the stimuli. upon reaching this stage you get the following passive effects.

• Resistance to poison, and necrotic damage.
• Immunity to disease, the poisoned condition, and the frightened condition. 

Visceral Consumption

Starting at 14th level, The feeling of utter horror and blight has completely left you, no longer do you feel the need to tear at your skin to get it out, however, not only do you miss the feeling, but you feel empty without it, all that's left is a deep hunger, which can be easily filled. Undenounced to the you, the Infestation has fully taken over, so lets begin with the changes. Where there was once a humanoid there is now an aberration, a form covered in sensory organs, hives, nests, etc. Your newfound applications of those are as followed.

(Passive)Lovecraftian Flesh-bag; You now have advantage on intimidation checks.

Mass Devouring; Once per long rest, as an action you can evoke the Infestation to splinter out of your form and claim the vitality of those around you. Creatures you choose within 60ft of you need to make a constitution saving throw equal to your spell save DC, on a failed save, the targets take 6d12 necrotic damage in addition to gaining the frightened effect. On a success they take half of the damage, in addition to this, you heal hit points, equal to the damage you rolled. Additionally, if the damage reduces a target to 0 hit points, the Infestation runs through their body, they then become completely consumed by the Infestation.
