The Mind Flayed

Abducted by mindflayers.

Telepath

Your psychic energy has allowed you to freely transmit your thoughts mentally with willing creatures within 120 feet of yourself that you can see. A contacted creature doesn’t need to share a language with you to understand your thoughts, but it must be able to understand at least one language. Your telepathic link to a creature is broken if you and the creature move more than 120 feet apart, if either of you is incapacitated, or if either of you mentally breaks the contact (no action required).

Psionics

You learn the Rite of Oracle as part of your Crimson Rite feature when you gain this subclass. While active you gain the following benefits:
- You can telepathically speak to any willing creature you can see within 60 feet of you. You don’t need to share a language with the creature, but the creature must be able to understand at least one language.
- You learn the mage hand cantrip. You can cast it without verbal or somatic components, and you can make the spectral hand invisible. The hand can perform the shove action, the target must succeed on an athletics or acrobatics check against your hemocraft save. If you already know this spell, its range increases by 30 feet when you cast it.
- You have resistance to psychic damage.

Blood Curse of the Tadpole

At 15th level, you hone your hemocraft to corrupt the minds and bodies. You gain the Blood Curse of the Tadpole for your Blood Maledict feature.
