ChallengeHard
Sunlight Aversion. While in bright sunlight the Crimson Stalker has disadvantage on attack rolls and stealth checks and its speed is reduced by 10 feet.
Blood Mark. If the Stalker hits with its bite, the target gains a Blood Mark. Blood Marks can be removed by lesser restoration or similar magic. Each time a Blood Mark spreads, the Stalker regains 5 hit points.
Shadowborn Stalker. The Stalker can attempt to hide even when only lightly obscured and while moving through trees it can take the Hide action as a bonus action on its turn.

Actions

Multiattack. The Crimson Stalker makes two attacks: one with its bite and one with its claw.
Bite. Melee Weapon Attack: to hit, reach 5 ft., one target. Hit: 15 () piercing damage. If the target is a creature, it must succeed on a Constitution saving throw or gain a Blood Mark and suffer 7 () necrotic damage at the start of each of its turns until the mark is removed. A creature can repeat the saving throw at the end of each of its turns, ending the effect on a success. Removing the Blood Mark requires a lesser restoration spell or similar magic.
Claw. Melee Weapon Attack: to hit, reach 10 ft., one target. Hit: 12 () slashing damage. If the target has a Blood Mark, the claw attack deals an extra 7 () slashing damage and the Blood Mark immediately spreads: each other creature of the Stalker’s choice within 10 feet that can see the marked creature must succeed on a Wisdom saving throw or become Frenzied for 1 minute. A Frenzied creature must use its action on its turn to spend the action attacking the nearest creature it can reach. A creature can repeat the saving throw at the end of each of its turns, ending the effect on a success. Magic that removes conditions also ends Frenzy.
Bloodcall. The Stalker rears up and emits a low, warbling cry. Each creature of the Stalker’s choice within 30 feet that can hear it and that is not a fiend or undead must succeed on a Wisdom saving throw or become Terrified for 1 minute. A terrified creature can repeat the saving throw at the end of each of its turns, ending the effect on a success. While frightened in this way a creature has disadvantage on ability checks and attack rolls while the Stalker is within line of sight. Once the Stalker uses Bloodcall, it cannot use it again until it finishes a short or long rest.

Reactions

Redirected Fury. When a creature the Stalker can see within 30 feet attacks an ally of the Stalker, the Stalker may immediately move up to 20 feet and make one claw attack against the attacker.

Legendary Actions

Shadow Glide. The Stalker moves up to half its speed without provoking opportunity attacks.

Notes for the game master

CR 5 creature. Use the Blood Mark mechanic to create control and secondary threats.
Frenzy effect forces enemies to act unpredictably; clarify target selection when a creature must attack the nearest creature.

Tactics

  1. Opening

    Use stealth to ambush from shadows and land a bite to apply a Blood Mark on a strong target. Immediately attempt to spread the mark with a claw to sow chaos.

  2. Mid-fight

    Use Multiattack to apply and spread Blood Marks. When two or more targets are Bleeding, use Bloodcall to frighten and control the battlefield.

  3. End of the fight

    Keep pressure on the party by maintaining Blood Marks and forcing allies into Frenzy. Prioritize disabling spellcasters or healers with Bloodcall and then finish weakened foes.

  4. Retreat

    If reduced to below half hit points, the Stalker seeks cover under heavy foliage and uses stealth to withdraw. If cornered and enraged, it fights until destroyed.

How it fights

Ambush from concealment at dusk
Target healers and casters first to spread blood marks and force allies into attacking them
Use Shadow Glide legendary action to reposition and avoid ranged focus

Who it attacks first

Medics and spellcasters
Wounded or isolated party members
Creatures with low Wisdom saves

Works well with

Works well with summoned swarms or lesser predators that can capitalise on Frenzied targets
Pairs with ambush traps or area denial effects to herd the party into kill zones

How to beat it

Dispel or remove Blood Marks with lesser restoration or remove curse style magic
Area fear or control spells like calm emotions can counter Frenzy and Bloodcall
Bright light and careful ranged tactics exploit the Stalker’s Sunlight Aversion

Ways to avoid a fight

Track and study from a distance to learn its hunting pattern
Attempt to lure it away with a controlled bleed or sacrificial prey
Use bright fires, mirrors, or lanterns to create safe corridors through its territory

Ecology

A hulking, wolflike predator the size of a warhorse. Its fur is matted and black but stained in places with crusted, dark red. Glowing veins of crimson run beneath the skin and pulsing light shows through around its eyes and along its flanks. Its maw is broad with needlelike teeth and its paws end in curved, sickle claws.

Behavior

Predatory and calculating. The Stalker prefers to strike at dusk and through moonlit nights. It observes a target quietly before striking, testing defenses with a quick bite. It thrives on chaos and uses its ability to incite Frenzy to turn allies against each other.

How it lives

Crimson Stalkers live alone or in loose pairs in deep, old-growth forests. They hunt large herbivores but will stalk humanoid prey for the thrill and the spread of bloodlust. Their presence alters local predator behavior making the forest more dangerous. They sometimes lair in hollowed groves where the ground is stained and bare.

Lair

A secluded grove ringed with dead undergrowth and bone, often under a canopy of twisted old trees. The area is shrouded in near-perpetual shadow and the Stalker can move through it without penalty. The lair grants the Stalker advantage on Stealth checks while within it.

Habitat
Temperate or primeval forests, especially old-growth and moonlit glades

Signs that it is near

Trampled and blood-stained clearings
Strange low warbling cries at night
Prey animals found in frenzied heaps, with multiple bite marks

Lore

Folklore calls it the Crimson Stalker or Bloodwolf. Hunters speak of its cry as an omen and say it used to be a spirit of vengeance that fed on war and slaughter. Some woods-witches claim it was born from a slashed ritual altar where blood was left under a new moon.

What drives it

To feed and spread the hunger for blood; it gains sustenance from chaos and the scent of terror

After the fight

Victims who survive the encounter with Blood Marks often suffer lingering nightmares and an urge to hunt. If a marked creature dies within 24 hours of being marked, nearby predators in the forest become unnaturally emboldened and may begin stalking the area for days. Local hunters will sometimes discover a ring of drained wildlife where the Stalker has fed.
