Shared nature

The rules of escalation.

01

Crossing

Obmils originate in the Negative Energy Plane, where their bodies cannot be seen because the plane consumes all visible light. Curious Obmil is their base visible form after crossing into the Material Plane.

02

Compulsion

Curious Obmil does not seek violence, yet nearby creatures are compelled to attack Curious Obmil. The method of that attack determines what Curious Obmil becomes.

03

Adaptation

Raging Obmil answers natural attacks, Aqua Obmil answers magic, and Sunshine Obmil answers crafted weapons. Each Obmil is immune to the category that created it.

04

Fusion

Compatible primary Obmils created within ten feet magnetize together. Pairs become Urkel Obmil, Ivy Obmil, or Greedy Obmil; all three primary Obmils together become Majesty Obmil.

Established forms

Ten creatures.
One living cycle.

White and Black Obmils are intentionally excluded from this registry. Every profile focuses on established Obmil lore.

Curious Obmil full creature portrait01
Base Material Plane form

Curious Obmil

About two feet tall

A small, chunky mushroom-shaped creature with feet, hands, and eyes. Curious Obmil is non-aggressive by nature, but its presence compels nearby creatures to try to attack it.

Appears when an Obmil crosses from the light-consuming Negative Energy Plane into the Material Plane.
Encounter profile
Its danger is escalation rather than intent. The compelled first strike can immediately create a form immune to the very method used against it.

  • Curious Obmil compels nearby creatures to attack
  • Curious Obmil transforms according to the attack used against it

Formation
A rare evolution shaped over a long life by solitude, sorrow, and extreme sensitivity to its surroundings.
Encounter profile
GoldCap Obmil is more valuable as an elusive witness or lore-bearing encounter than as an ordinary combat threat. Hidden glades and sources of pure magic are associated with GoldCap Obmil sightings.

Majesty Obmil

Major encounter form

Formation
Raging Obmil + Aqua Obmil + Sunshine Obmil, all still in their primary stages and all within ten feet. Secondary forms cannot substitute.
Encounter profile
Majesty Obmil creates a feedback loop: spores become Curious Obmils, Curious Obmils compel attacks, attacks create primary Obmil forms, and nearby primary Obmils can fuse into more advanced forms.
ESTABLISHED TRAITS
  • Majesty Obmil continuously produces spores
  • Spores rapidly become Curious Obmils
  • Majesty Obmil can restart the entire transformation and fusion cycle
