Crimson Stalkers

Infectious Madness. When the Crimson Stalker deals damage with a melee attack, the target must succeed on a DC 12 Constitution Saving Throw or contract the C-Virus (incubation: 1d4 hours). Those inflicted gain the "Sadistic Urge" condition: At the start of each turn, roll a d20- On a 10 or lower, they must attack the nearest creature (ally or foe) with reckless abandon, gaining advantage on the attack but granting advantage to attacks against them until their next turn.

Sadistic Frenzy. The Crimson Stalker has advantage on attack rolls against creatures below half their hit points, reveling in weakness. If reduced to 0 HP, it makes one final attack as a reaction before dying, often self-inflicted if no targets are available (dealing 1d6 psychic damage to nearby witnesses from the horror.)

Blood Weep. At the start of its turn, the Crimson Stalker takes 1d4 necrotic damage from internal hemorrhaging but gains +1d4 to its next damage roll, fueled by pain.

Multiattack. The Crimson Stalker makes two attacks; One with its bite, and one with its claws.

Bite. Melee Weapon Attack. +5:{"diceNotation":"1d20+5","rollType":"to hit","rollAction":"Bite"} to hit, reach 5ft., one target. Hit: 6 (1d6+3) piercing damage, plus Infectious Madness.

Claws. Melee Weapon Attack. +5:{"diceNotation":"1d20+5","rollType":"to hit","rollAction":"Claws"} to hit, reach 5ft., one target. Hit: 8 (2d4+3) slashing damage. On a hit, the target is grappled (escape DC 13), and the Crimson Stalker can use a bonus action to taunt, forcing a DC 12 Wisdom Save, or the target takes 1d6 psychic damage from the horrifying images.

Sadistic Surge (Recharge 5-6). The Crimson Stalker lets out a blood-curdling laugh, targeting up to three creatures within 15ft. Each must succeed a DC 12 Wisdom saving throw or be frightened for one minute, compelled to harm themselves or others.

Taunt. The Crimson Stalker taunts a grappled victim, forcing a DC 12 Wisdom Save, inflicting 1d6 psychic damage on a failed save.

Suicidal Final Charge. The Crimson Stalker makes one final, suicidal attack when dropped to 0 HP. This attack can be made against one other creature, or itself if no other creature is nearby.
