Constant Spells

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.

Clarity Vulnerability

The first time in a round that a creature within 30 feet of the miastrilek critically succeeds on a saving throw against a poison or disease or fully recovers from either such affliction via magic or another effect, the demon takes 6d6 mental damage.

Change Shape (concentrate, divine, polymorph)

The miastrilek can take on the appearance of any Small or Medium humanoid. This doesn't change their Speed but does prevent them from making fangs Strikes.

Spew Pollution (divine)

Rituals

Demonic Pact

---

When in their true form, miastrileks have a spider-like appearance. However, they prefer humanoid forms when interacting with mortals, posing as rich or influential figures such as nobles, merchants, or leaders of criminal organizations.

Polluters Of Flesh

Miastrileks are demons associated with pollution and corruption, but unlike the omox (a demon that rises from souls who routinely befouled and polluted their environmental surroundings in life), the miastrilek's sin is more focused on the pollution and corruption of the flesh—such as those who in life ran complex webs of corruption in society that manufactured and distributed drugs that ruined communities, or used pollution and toxins to torture and transform their victims.
