Void Leech

Proficiencies: Stealth +5

Senses: Senses warmth and fluid through bulkheads within 30 feet, Unharmed by vacuum, cold, and radiation

Seal-Slider. The void leech moves through gaps, vents, and suit joins; standard cover and closed bulkheads do not stop its approach unless fully airtight and inspected.

Latched Feeding. While attached to a creature, the leech drains 1d4 Vitality from it automatically at the start of each of the leech's turns and compromises the host's void-seal. Removing it takes an action and a Strength or Medicae check DC 12; tearing it free on a failed check deals 1d4 rending damage to the host.

Silent Attach. Melee Attack: +4 to hit, reach 5 ft., one target (with Advantage if the leech is unnoticed). Hit: 1d4 piercing damage and the leech attaches to the target. A victim in a sealed suit may not notice until the suit alarm or the cold spot; an Awareness check DC 13 spots it.

Constrict Seal. The leech tightens around an attached host's suit joins. The host's void-seal integrity drops one step; in vacuum, a breached seal starts a suffocation countdown at the GM's clock.

Morale: Mindless appetite: detaches only from fire, extreme cold, or a dead host, and drifts away sluggish and swollen.

Tactics: Play it as dread and procedure: sweep checks, buddy inspections, the one crawlspace nobody swept. An attached leech mid-combat forces a choice between fighting on while it drains and spending actions on removal under fire.

Loot / Evidence / Hooks: A gravid leech's fluid sacs fetch a grim price from Magos Biologis buyers, if anyone is willing to carry them home.

A Void Leech is a flat, patient parasite adapted to hulls and hard vacuum, sliding through seals to fasten onto warmth and fluid. The horror is not the damage; it is where it is attached, and what removing it costs.

Use this enemy during void work and derelict crawls, when suit integrity and calm hands are the real Vitality.

Low durability, stealthy attachment, suit and seal damage, drain over time, panic-inducing rather than lethal in the open — worse in vacuum.

Seal-Slider. Moves through gaps, vents, and suit joins; standard cover and bulkheads do not stop its approach.

Latched Feeding. Once attached, drains Vitality automatically each round and compromises the host's void-seal; removal requires a check, and tearing it free costs extra.

Silent Attach. Stealth approach and latch; the victim may not notice until the suit alarm or the cold spot.

Constrict Seal. Damages the host's suit integrity; in vacuum, this converts a parasite problem into a countdown.

Morale: Mindless appetite: detaches only from fire, extreme cold, or a dead host, and drifts away sluggish and swollen.

Tactics: Play the leech as dread and procedure: sweep checks, buddy inspections, the one crawlspace nobody swept. An attached leech mid-combat forces an awful choice — fight on while it drains, or spend actions on removal under fire. In vacuum scenes, one leech can headline the encounter.
