Monstrous Mondays: Wyrdcat

 I am working on another piece of something that may or may not involve my "The One Who Remains."  Think of this as a warm-up sketch an artist would do before getting into their main composition. 

As it turns out, this also makes a decent OGL-ready version of a Displacer Beast. This is based on a monster we used to use called a "Tessercat." 

Wyrdcat

Dimensional Apex Predator

“It isn’t invisible. It’s just in three places you’re not.”

- Notes from the Archives of Killian Mazior

The Wyrdcat is a predator from beyond the edges of known planes, not born of one world, but between them. It is not native to any reality, and perhaps not even alive by most definitions. When Killian’s Tower began drawing in unstable planar energies, the Wyrdcat slipped through. A wandering apex hunter, now trapped within the folds of fractured dimensions.

Though feline in form, the Wyrdcat is a thing of quantum uncertainty and temporal stutter. It appears as a sleek, panther-like creature with oily black fur, three shadow-laced tails, and eyes that glint in colors no one can name. Its form pulses with fractured reflections. At any given moment, it may exist in multiple nearby positions, flickering like an unsynced illusion.

It hunts with the precision and cruelty of a big cat; stalking, pouncing, toying with prey before the kill. The laws of space and time bend around it. Some say it sees not just where a creature is, but where it was and will be. Those who survive a Wyrdcat encounter speak of claws that cut through armor, wounds that reappear after healing, and psychic echoes that return in dreams.

Behavior

Solitary Apex Predator: The Wyrdcat hunts alone. It marks its territory across multiple overlapping realities. If another apex predator enters its distorted hunting grounds, it becomes immediately aggressive.

Reality Drifter: The Wyrdcat can manipulate its form to align with different versions of reality. This shift can cause localized changes in reality, resulting in distorted probability fields. (This results in the players needing to use different dice to roll for initiative, to hit, and damage. It can also cause the local "rules" to shift between editions of the game.)

Mirror Flicker: It always appears in three semi-distinct forms: one solid, two afterimages or preimages. Only one is real at any time, and it may shift between them without warning.

Dimensional Stalker: It may pursue prey even after they plane shift, teleport, or escape into another zone of the tower. It remembers where they will be.

The Wyrdcat is a sleek, black-furred feline predator from beyond the known planes. Though it resembles a panther or great jungle cat, the Wyrdcat’s form flickers unnaturally between overlapping dimensions, accompanied by afterimages that move out of sync with its body. Its three shadow-tailed limbs seem to lag or stutter through space, and its eyes shimmer with alien colors beyond mortal comprehension.

Wyrdcats are not native to any world. They are planar anomalies. Believed to be either accidents of cross-dimensional entropy or the predatory echoes of something far older and deeper. The creatures now prowl the fringes of unstable magical structures such as witch gates, collapsed covensites, and reality-warped ruins.

Though bestial in nature, Wyrdcats hunt with a cruel cunning. They stalk arcane spellcasters and dimensional travelers, and are particularly drawn to witches, warlocks, and those who have tampered with interplanar forces.

The Wyrdcat attacks via a claw/claw/bite routine common to large cat predators. Each claw can do 2-8 (2d4) hp worth of damage, while its bite can do 2-12 (2d6).

Mirror Flicker (Special Defense)

The Wyrdcat constantly flickers between three visible forms. It functions as if under a permanent mirror image spell with two false images. The true form randomly shifts every round. Attacks against the creature have a 66% chance to target an illusion unless the attacker has true seeing or similar magic.

Planar Pounce (Special Attack)

Once per encounter, the Wyrdcat may teleport up to 30 feet to attack as if using a dimension door. This grants it +2 to hit and imposes a -2 penalty on the target's surprise roll.

Edition Flux (Optional Rule)

Once per turn, the GM may declare that the Wyrdcat is using mechanics from a different edition (i.e., switch initiative methods, AC rules, etc.). Players must quickly adapt.

The Wyrdcat attacks via a claw/claw/bite routine common to large cat predators. Each claw can do 1d8+5 hp worth of damage, while its bite can do 2d6+5.

Mirror Flicker (Su): The Wyrdcat exists partially in multiple dimensions. It is constantly under an effect similar to mirror image, generating 2 illusory copies of itself. These cannot be dispelled normally. True seeing reveals the true form.

Planar Pounce (Su): Once per day as a free action, the Wyrdcat may teleport up to 30 feet before making a full attack. This does not provoke attacks of opportunity.

Edition Flux (Ex): Once per encounter, the Wyrdcat may twist reality, forcing all initiative to be rerolled using d10 (2e style) or d6 (1e style), randomly determined. It may also alter damage reduction, attack styles, or magic resistance at the GM’s discretion.

Mirror Flicker.

The Wyrdcat projects two illusory versions of itself, similar to the mirror image spell. At the start of each turn, roll 1d6. On a 1–4, the attack targets an illusion, which vanishes; on a 5–6, the attack targets the real creature. If all images are destroyed, they regenerate at the start of the Wyrdcat’s next turn.

Planar Pounce (1/Day).

As a bonus action, the Wyrdcat teleports up to 30 feet to a space it can see and makes a full multiattack.

Reality Flux (Recharge 5–6).

The Wyrdcat distorts the battlefield. Until the end of its next turn:

  • All initiative rerolls use a d10 or d6
  • Saving throws use the 3e categories (Fort/Ref/Will).
  • AC is treated as descending (lower = better) for targeting purposes.

This affects PCs and NPCs alike. Creatures with truesight are unaffected.

Actions 

Multiattack. The wyrdcat makes two attacks with its claws and one attack with its bite.

Claw.

Melee Weapon Attack: +8 to hit, reach 10 ft., one target

Hit: 12 (2d6 + 5) slashing damage.

If the target is a spellcaster concentrating on a spell, it must make a DC 15 Constitution saving throw or lose concentration due to the Wyrdcat’s disruptive phasing claws.

Bite.

Melee Weapon Attack: +8 to hit, reach 5 ft., one target

Hit: 16 (2d10 + 5) piercing damage.

If this attack reduces a creature to 0 hit points, the Wyrdcat may teleport up to 30 feet as a free action at the start of its next turn (Planar Reflex Surge).
