Aberrant Hunter

HP: 58 AC: 14 DR: 0 Attack: 2d8+2
Lurking hunters found in caverns and dungeons, their rasping tongues flicking like whips as they drag prey screaming into the dark.

Abyrion Border Strider

HP: 33 AC: 12 DR: 0 Attack: 1d10+2
Born where forests darken into the abyssal wilds, Border Striders carry messages for ancient spirits and guard the invisible thresholds of nature. Ash-bright hooves mark every line they patrol. They offer a single warning before charging through anything that defies the wild's domain.

Abyssal Dredge

HP: 245 AC: 16 DR: 5 Attack: 2d10+6, 2d10+6
The floor of the abyss given ambulatory form - heavy, slow, and patient in the way geology is patient. It senses vibration through ground and deep water, and it does not experience pain.

Abyssal Skulker

HP: 18 AC: 11 DR: 0 Attack: 1d4
A hunched shadow that clings to corners and crevices, its form barely distinguishable from the darkness it inhabits. The abyssal skulker doesn't hunt so much as wait - patient, silent, unmoving for hours until prey wanders close. Its eyes, when they open, are pits of deeper black that drink in light rather than reflect it. […]

Acid Slime

HP: 29 AC: 12 DR: 0 Attack: 1d8+1
A living mass of corrosive ooze that dissolves anything it touches. It reacts to movement and heat, sliding toward prey without thought or fear. Its acid quickly damages metal, burns flesh, and can ruin weapons and armor if they strike too deep. Chalk, mud, water, and milk can neutralize the acid.

Acid Spewer

HP: 52 AC: 13 DR: 1 Attack: 2d6+3
A massive reptilian beast that builds nests in corrosive swamps and caves. It sprays pressurized acid from its gullet, melting armor and flesh while keeping its foes at a distance. Its hide is thick and naturally resistant to acid, letting it wallow in pools that would dissolve most creatures. Players must neutralize any lingering acid […]

Addlick

HP: 42 AC: 14 DR: 0 Attack: 1d4+2, 1d4+2
A winged cat that drops like thunder, pinning prey with a single shocking impact.

Adult Black Dragon

HP: 185 AC: 18 DR: 2 Attack: 2d10+6, 2d8+6, 2d8+6
An adult black dragon in its prime, a gleeful sadist ruling a rotting expanse of swamp and ruin. It dissolves prey in acid and prefers a slow kill to a quick one, often setting weaker creatures against each other simply to watch them suffer. Paranoid and grudge-bound, it remembers every slight and repays each a […]

Adult Blue Dragon

HP: 185 AC: 18 DR: 2 Attack: 2d10+6, 2d8+6, 2d8+6
An adult blue dragon in its prime, ruling a stretch of deep desert with cold, calculating cruelty. It lairs in glass tunnels bored beneath the dunes, ambushes caravans with a spear of lightning, and prizes gemstones above gold - its hoard sorted and arranged with a vanity that borders on obsession. A blue does not […]
