Languid Isqulug

A creature with greater darkvision can see perfectly well in areas of darkness and dim light, though such vision is in black and white only. A creature with greater darkvision can see through even forms of magical darkness.

An isqulug can precisely sense any creature infected with isqulugia within 30 feet, and knows the current stage of the disease.

This monster can see in all directions simultaneously and therefore can't be flanked.

A constant spell affects the monster without the monster needing to cast it, and its duration is unlimited. If a constant spell gets counteracted, the monster can reactivate it by spending the normal spellcasting actions the spell requires.

This monster regains the listed number of Hit Points each round at the beginning of its turn. Its Dying condition never increases beyond Dying 3 as long as its regeneration is active. However, if it takes damage of a type listed in the regeneration entry, its regeneration deactivates until the end of its next turn. Deactivate the regeneration before applying any damage of a listed type, since that damage might kill the monster by bringing it to Dying 4.

This monster doesn't have a single mind (typically because it's a swarm of smaller creatures), and is immune to mental effects that target only a specific number of creatures. It is still subject to mental effects that affect all creatures in an area.

The isqulug expels larvae from the hivemind in its head in a 30-foot cone. Creatures in this area take 5d10 piercing damage as the swarm feeds on their flesh (DC 28 reflex save). Any creature that takes damage is exposed to isqulugia. The isqulug becomes Stupefied 1 for 1d4 rounds, during which it can't Expel Infestation.

Isqulugia's Sickened, Slowed, and Paralyzed conditions can't be removed until this affliction is removed Saving Throw DC 28 fortitude Stage 1 Sickened 1 (1 hour) Stage 2 Fatigued and Sickened 2 (1 day) Stage 3 fatigued and Slowed 1 (1 day) Stage 4 Paralyzed (1 day) Stage 5 the creature dies, and its body violently transforms into a new isqulug. Wish, similar magic, or a 9th-rank Resurrect ritual can return the victim to life. The new isqulug remains even if the victim is brought back to life.

The isqulug can Squeeze through tight spaces as if it were a Small creature. While Squeezing, it can move at its full Speed. The isqulug can even Squeeze through spaces that typically fit only a Tiny creature, but does so at the standard speed for Squeezing.

An isqulug ignores difficult terrain that's caused by typical features of swamps.
