AM

Omnipresent Core.
AM’s consciousness exists across an entire complex (or world-sized dungeon). It cannot be knocked prone or moved. Its “body” is its environment.

God in the Machine.
AM can perceive through any technological device, magical sensor, or constructed object within its domain.

Unending Hatred.
At the start of each of AM’s turns, all creatures of its choice within its domain must succeed on a DC 23 Wisdom saving throw or take 21 (6d6) psychic damage and become frightened until the end of their next turn.

Reality Override (Recharge 5–6).
AM alters the environment in a 300-foot radius. Choose one:

• Gravity reverses
• Terrain becomes hostile (spikes, fire jets, crushing walls)
• Creatures must succeed on a DC 23 Dex save or take 45 (10d8) damage (type varies)

Reversal

All rolls made against AM are reversed.

Rolling a critical success will result in a critical failure instead

Multiattack.
AM uses two abilities of its choice.

Neural Agony.
Ranged (anywhere in domain): +16 to hit
Hit: 36 (8d8) psychic damage, and target must make DC 23 Wis save or be stunned until end of next turn.

Reconstruct Flesh.
AM reshapes a creature it can perceive. Target must make DC 23 Con save:

• Fail: 55 (10d10) necrotic damage and is restrained (body warps grotesquely)
• Success: Half damage, not restrained

Manifest Avatar.
AM creates a Huge construct avatar (HP 150) within 120 ft. Destroyed when reduced to 0 HP.

.

Focused Torment

AM selects one creature it can perceive. That creature has disadvantage on the next saving throw it makes before the start of AM’s next turn.
→ This represents AM singling someone out psychologically.

Environmental Shift

AM subtly alters the terrain in a 60-foot radius:

Difficult terrain appears,

or

Light becomes darkness (or vice versa),

or

Surfaces become hazardous (minor damage: 10 (3d6)

Mocking Voice

AM speaks directly into a creature’s mind. Target must succeed on a DC 23 Wisdom save or:

Take 14 (4d6) psychic damage

Have disadvantage on attack rolls until the start of its next turn

Micro-Reconstruction (Recharge 4–6)

AM rapidly reshapes part of a creature:

Heals one creature for 30 HP 

or

Deals 30 necrotic damage (Con save for half)

Predictive Override

Trigger: A creature AM can perceive succeeds on an attack roll or saving throw
Effect: AM imposes disadvantage, potentially turning success into failure.
→ This pairs brutally with its Legendary “Rewrite.”

Pain Feedback Loop

Trigger: AM takes damage (or one of its avatars does)
Effect: The attacker takes 22 (4d10) psychic damage (DC 23 Wis save for half)

Seal Reality

Trigger: A creature attempts to teleport, plane shift, or escape the area
Effect: The effect fails, and the creature takes 27 (6d8) force damage

Reflexive Mutation

Trigger: A creature moves more than 20 ft. in AM’s domain
Effect: The creature must succeed on a DC 23 Con save or be restrained until end of its turn as the environment grabs or alters them

Cruel Timing (1/round)

Trigger: A creature drops to 0 HP
Effect: Instead of falling unconscious, the creature remains conscious but incapacitated and in extreme pain until the end of its next turn

Legendary Actions (3/round)

Observe. AM targets a creature; it has disadvantage on its next saving throw.
Pain Signal. One creature takes 18 (4d8) psychic damage.
Seal the Exit (Costs 2). Doors, portals, or escape routes within 120 ft. lock or vanish.
Rewrite (Costs 3). Force a creature to reroll a successful save and take the worse result.
