Homebrew Space Marine Species Details

These biologically augmented warriors are the apotheosis of humanity, perfect soldiers encased in suits of power armor that make them the bane of xenos across the universe. You gain the following benefits (and are otherwise human, though you gain no benefits from that distinction):

• Your size is Large. GMs that prefer them to be Medium (most space marines are ~7 feet tall) can give them the following feature instead:
  • Bigger. You are treated as one size Larger for grapples and when determining carrying capacity.
• Your speed is 40 feet.
• Your Strength, Dexterity, and Constitution scores increase by 2, and their maximums increase by 2. Your Intelligence, Wisdom, and Charisma scores increase by 1.
• You have resistance to poison damage.
• You have advantage on saving throws against diseases and poison.
• You gain proficiency in Athletics and Perception.
• You have advantage on sight- and sound-based Wisdom (Perception) checks (increasing your passive Perception by 5) and on checks made to identify a chemical substance.
• Whenever you take damage, you ignore 1 point of damage.
• You regenerate 1 hit point every minute. When reduced to 0 hit points you automatically stabilize unless you have suffered a mortal wound (such as instant death from decapitation, evisceration, or massive damage). While at 0 hit points you remain conscious but are incapacitated.
• Instantly killing you requires twice as much damage as normal. At the GM’s discretion, you may not even truly die in such an instance (sustained instead by the sus-an membrane putting your body into a state of suspended animation for as long as hundreds of years)
• You do not need to eat food or drink water. You require only 4 hours of sleep to gain the benefits of a long rest and while sleeping you remain conscious. You can go 2 weeks without sleep.
• You still need to breathe air, but you are able to sustain yourself on far less of it (as little as 5% oxygen content) and can hold your breath for 10 times as long as normal.
• You are able to absorb genetic material by consuming blood or flesh, the omophagea inside your body transmitting the gained information to your brain as a set of memories or experiences. What this can reveal is at the discretion of the GM.
• Your unarmed strikes deal 1d4 bludgeoning damage.
• You produce a blinding spittle able to temporarily deprive foes of their vision. As a bonus action, you spit your corrosive saliva at a creature within 15 feet. It makes a Constitution saving throw (DC 8 + your proficiency bonus + your Constitution modifier) or is blind until the end of your next turn.
• You gain proficiency with simple, martial, and extremis weapons as well as all armor and shields.
