Homebrew Fire flayer Species Details

The progeny of a fire giant and a mind flayer. 

Mind flayers, also called illithids, are the scourge of sentient creatures across countless worlds. Psionic tyrants, slavers, and interdimensional voyagers, they are insidious masterminds that harvest entire races for their own twisted ends. Four tentacles snake from their octopus-like heads, flexing in hungry anticipation when sentient creatures come near.

Fire flayers can devour memories and use limited psionic abilities from their illithid parent. 

Master crafters and organized warriors, fire giants dwell among volcanoes, lava floes, and rocky mountains. They are ruthless militaristic brutes whose mastery of metalwork is legendary.

Fire giants shun cold as much as their cousins the frost giants hate heat. They can adapt to cold environments with effort, though, keeping their hearth fires burning bright and wearing heavy woolen clothing and furs to stay warm.

Fire flayers are larger than the average human and have a reddish tint to their skin. 

Lifespan: 200-300 years/ same maturity as humans age-wise (fully maturing between 18-25)

Size: Medium

Speed: 30 feet walking, 15 hovering/flying

Dark vision: You can see in dark and dim conditions. You can see in dim light up to 60 feet as if it was bright light, and up to 30 feet in darkness as if it was dim light.

Tentacular Morphism: You have the ability to shift one of your hands into tentacles (you decide which, but it will be permanent.) So long as you are not wielding a weapon in that hand, you may transform it into tentacles that are 5 feet at maximum length. As an action in combat, you may use them to grapple a target. They must make a strength saving throw versus your dexterity or intelligence roll (you decide.) You may also use these tentacles to absorb the memories of a grappled, incapacitated, or otherwise unresisting opponent, to acquire 1d4 temporary hitpoints. This can only be used every other turn versus an opponent. 

Psionics: You know the message cantrip. When you reach the 5th level, you may cast disguise self once per long rest. At level 15, you can use the spell detect thoughts once per long rest. At level 17, you can cast disguise self up to twice per long rest. At level 20, you can cast disguise self three times per short rest, and detect thoughts twice per long rest.

Hybrid Nature: You have two creature types: humanoid and aberration. You can be affected by any spell, object, condition, or other game effect which applies to either of these traits.

Languages: You can speak, read, and write in Common, Deep Speech, and one other language of your choice.

Deep heritage: You have a weakness (take twice the damage) from radiant damage. You also have disadvantage on saving throws versus radiant damage attacks. Conversely, you have half resistance (-5 to damage) to psionic attacks, and advantage on saving throws versus psionic attacks.

Mind Flayer Bloodlines: Advantage in recognition of geometric patters/ symbolic hieroglyphs.

Fire Giant Bloodline: Attacks that use fire do not have advantage against you. Further more, you are well suited to dry, hot environments.

Appearance: As a half-breed, you retain some features of your parents. You're slightly larger than average human size, and you retain a reddish tint to your skin. Your hands are longer than the average human, and more slender. Your hair is usually dark colors, such as crimson, black, dark brown, or Dark Purple.
