Traits

Parasite Control

When an Asyther Lurker attaches to a giant, it can control its actions as if it were a puppet.

Massive Size

The Asyther Lurker has disadvantage on checks to avoid being grappled but automatically grapples any creature it attacks.

Actions

Tentacle Grab

Melee Weapon Attack: +12 to hit, reach 20 ft., one target. Hit: 34 (4d10 + 5) bludgeoning damage, and the target is grappled (escape DC 19). While grappled, the target is restrained until the grapple ends.

Infest

The Asyther Lurker injects its larvae into a grappled giant. The affected giant must succeed on a DC 20 Constitution saving throw or take 55 (10d10) poison damage and be poisoned for 1 minute.

Psychic Drain

The Asyther Lurker targets one intelligent creature it can see within 60 feet. The target must succeed on a DC 20 Intelligence saving throw or take 45 (10d8) psychic damage and the Asyther Lurker regains hit points equal to half the damage dealt.

Reactions

Lurking Shadow

When a creature within 30 feet attacks the Asyther Lurker, it can use its reaction to impose disadvantage on the attack roll.

Combat Behavior

Tactics


• Ambush from concealment using their size and stealth.
• Infect the largest or most powerful giant to create chaos among allies.
• Use psychic attacks to incapacitate smaller foes.

Combat Style

They employ hit-and-run tactics, forcing their enemies to strike at great disadvantage while inflicting psychic damage.

Morale

Asyther Lurkers fight until their host is slain. If it appears that they will be killed, they will attempt to escape and seek another host.

Monster Description

The Asyther Lurker is a monstrous aberration birthed from the nightmares of ancient evils. Its form resembles a grotesque hybrid of a leech and a giant octopus, with writhing tentacles and a distended, pulsating body that glows with an eerie bioluminescence. These parasites are said to be the remnants of a forgotten realm, where they once fed on the primordial energies of giants, using their immense size against them. Lurkers are drawn to the powerful and the unwary, seeking to infiltrate the minds and bodies of the giants they target, worming their way into the host's psyche and corrupting their very being.

Legends speak of entire tribes of giants vanishing, only to re-emerge as mindless thralls under the lurker's control. The Asyther Lurker's connection with the giants is not merely parasitic; it thrives on fear and despair, using the giants' might to spread chaos. When attached, it pulls at the strings of its host's consciousness, forcing them to act against their will. Large groups of giants infested by several lurkers can become formidable foes, capable of great destruction as they succumb to the lurker’s twisted desires. The trauma of its presence lingers long after its departure, leaving behind traumatized minds and shattered souls.

Monster behavior

Asyther Lurkers are cunning predators that employ a strategy of stealth and ambush. They often lurk in the shadows of giant settlements, waiting for the opportune moment to strike at the vulnerable. Once they have attached to a host, they exploit the giant's physical strength while instigating fear and paranoia within their ranks. The lurkers are known to whisper dark thoughts into the minds of their infected hosts, sowing discord and mistrust among them. They thrive in environments where they can take advantage of their innate stealth and overwhelming size, launching surprise attacks that cripple entire communities.

Ecology

The Asyther Lurker occupies a unique ecological niche as a parasite of the giant race. In many ways, they mimic the role of the predator and prey relationship seen throughout nature, albeit in a much more sinister context. By infesting giants, they ensure their continuous existence, feeding on the physical and emotional energies of their hosts. Their role extends beyond mere survival; they disrupt the natural balance of their environment by transforming powerful beings into agents of chaos. Once a giant is consumed and emptied of its will, the lurker disperses to seek out new hosts or return to its lair, perpetuating a cycle of destruction.

History

The origins of the Asyther Lurker remain shrouded in mystery, but ancient texts suggest they were spawned from a cataclysmic event during a war between the gods. Following the cataclysm, remnants of these divine energies twisted into aberrations that sought to lash out against their creators and any beings that represented the natural order, particularly giants. Over centuries, their presence has been felt in various regions, often associated with unexplained tragedies or sudden madness among giant populations. Tales of their appearance are often told as cautionary tales among both humanoids and giants alike, warning of the greed that draws them close and the dire consequences of unsettling the balance of power in the realms. Their emergence has led to the downfall of powerful giant kingdoms, long lost to history, and serves as a grim reminder of the lurking horrors that dwell beyond mortal understanding.
