Disgustingly Resilient. Whenever the plague marine takes damage, reduce that damage by 3 (minimum 1). It is immune to poison and disease.
Cloud of Flies. Creatures that start their turn within 10 feet of the plague marine make a Toughness Save DC 14 or have Disadvantage on their next attack roll. A creature that fails this save twice in one scene suffers Corruption exposure.
Inexorable Advance. The plague marine cannot be Pinned or Suppressed, and its Movement cannot be reduced below 15 feet.
Blight Bolter. Ranged Attack: +5 to hit, range 80/240 ft., one target. Hit: 2d8 + 2 ballistic damage plus 1d4 poison damage.
Plague Knife. Melee Attack: +7 to hit, reach 5 ft., one target. Hit: 2d6 + 4 piercing damage, and the target makes a Toughness Save DC 14 or contracts a festering sickness: it takes 1d4 poison damage at the start of each of its turns until it succeeds a Toughness Save DC 14 at the end of one of its turns.
Blight Grenade. The plague marine lobs a rotting grenade at a point within 40 feet. Creatures within 10 feet of the point make an Agility Save DC 13, taking 3d6 poison damage on a failure or half on a success. The zone counts as toxic ground until the start of the plague marine's next turn.
Morale: Does not make Morale checks; rot and devotion have burned out its fear.
Tactics: Walk straight through kill zones cover cannot save it from, foul chokepoints with blight grenades, and let the flies and sickness grind down anyone who stands and fights.
