Simic Hybrid

The Simic Combine uses magic to fuse different life forms together. In recent years, they have extended this research to humanoid subjects, magically transferring the traits of various animals into Humans, Elves, and Vedalken. The goal of the so-called Guardian Project is to build a Simic army of superior soldiers, perfectly adapted to a variety of combat situations. These hyper-evolved specimens are called Simic hybrids, though they sometimes call themselves guardians.

Creating a Simic Hybrid

Ability Score Increase. Your Constitution score increases by 2, and your Intelligence score increases by 1.
Age. Simic Hybrids are created at adulthood as either Humans, Vedalkens, or Elves. Their maximum life expectancy is probably reduced.
Size. Simic Hybrids are the same size as the race that they were created from. Your size is Medium.
Speed. Your base walking speed is 30 feet.
Darkvision. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can't discern color in darkness, only shades of gray.
Animal Enhancements. Your body has been altered with animal characteristics. You choose one animal enhancement now and one at 5th level.

• Manta Glide (1st level). You have ray-like fins that you use as wings to slow your fall or allow you to glide. When you fall and are not incapacitated, you can subtract up to 100 feet from your fall when calculating your fall damage and can move horizontally 2 feet for every 1 foot you fall.
• Nimble Climber (1st level). You have a climb speed equal to your walk speed.
• Underwater Adaptation (1st level). You can breathe air and water, and you gain a swim speed equal to your walking speed.
• Grappling Appendages (5th level). You have two special appendages growing alongside your arms. Choose whether they're both claws or tentacles. As an action, you can use one of them to grapple a creature. Each one is also a natural weapon, with which you can use to make an unarmed strike. If you hit, they do 1D6 + your strength modifier bludgeon damage. Immediately after hitting, you can try to grapple the target as a bonus action. These appendages are not dexterous enough to use weapons, magic weapons, and other specialized equipment.
• Carapace (5th level). Your skin in places is covered by a thick shell. You gain a +1 to your AC when not wearing heavy armor.
• Acid Spit (5th level). As an action, you can spray acid from glands in your mouth, targeting one creature or object you can see within 30 feet of you. The target must make a Dexterity saving throw against a DC of 8 + your proficiency bonus + your Constitution modifier. The target takes 2D10 acid damage if they fail. The damage increases to 3D10 at 11th level and 4D10 at 17th level. You can use this up to your Constitution modifier's worth of times per long rest.

Languages. You can speak, read, and write Common and your choice of either Elven or Vedalken.

Racial Options

There are a few options to make your character fit the ideas you may have. The Ability Score Increase, Size, and even Languages can all be customized to better fit your character's history. Maybe you come from a very hardy people, like the Dwarves, but your character can't handle even the slightest cold breeze, but they make up for it with their incredible intellect. You could have been born of the tall and long Elves, but you find yourself barely coming up to some of their hips. Your Goblin may have been adopted by a couple of loving Genasi and they taught you to speak Primordial instead of Goblin. The options listed under your chosen race are just suggestions to easily fit your character within their culture's society, but you can change things up to make your character truly yours. There may be limitations set by the DM; rarely will you find a Large Fairy or a Tiny Goliath, but if you have a good story-driven reason for different character options, anything can be possible. Below are open-ended options for customizing your race.
Ability Score Increase. Increase one ability score by 2, and increase a different one by 1.
Size. Your size is within one size option of your race's average size.
Languages. You can speak, read, and write Common and one other language that you and your DM agree is appropriate for the character.
