Striderbeak

A bipedal avian beast with powerful talons, expressive eyes, and vibrant biome-colored plumage. Originally feared as apex predators, they've become prized mounts among skilled riders.

Biome Variants (Plumage + Traits)

Each wild Striderbeak has a distinct color and passive trait based on its native biome. Players can find, tame, or breed variants with different passive abilities.

Special Traits

Terror Sprint (Recharge 4–6)

As a bonus action, the Striderbeak can enter a sprint state for 1 round, doubling its movement speed and gaining advantage on Dexterity saving throws.

Avian Agility

The Striderbeak may Dash, Disengage, or Dodge as a bonus action when not carrying more than one rider.

Bond Instinct (Mount Feature)

When bonded to a rider (Bond Level 2+), it automatically moves to intercept ranged attacks, once per short rest, it can impose disadvantage on one ranged attack against its rider.

Pack Mimicry

Striderbeaks trained in groups learn to imitate each other’s responses. If another Striderbeak within 30 ft uses Terror Sprint, this one may use it as a reaction.

Actions

Beak Strike

+6 to hit, 5 ft reach.
Hit: 2d8 + 4 slashing damage.

Talons (Mount-Only Attack)

If ridden and charging at least 20 ft straight toward a target, the rider may command the mount to make a Trampling Talon attack as a bonus action:
DC 14 Strength save or take 2d10 + 4 slashing and be knocked prone.

  • Bond Level 2: +10 ft speed and mount obeys combat orders
  • Bond Level 3: Rider can use reaction to give mount an action (Dash, Attack, Disengage)

Breeding & Herds (Optional System)

  • Striderbeaks can be bred if two mounts of different biomes are paired during downtime and cared for (Animal Handling DC 15). Offspring inherit coloration and traits (either parent or hybrid).
  • Herds may defend territory and contain Alpha Striderbeaks (CR 4–6) with unique, fused biome traits and intelligence.
