Light, Biomes and Hazards

Light Levels, Biome Types, Threat Levels, the Hazard Severity table and the Survival Rules.

Light Levels

Light changes how far a Persona can see. Darkness is total: no sight at all, and the Persona is Blind.

Light Levels
Light	Vision Range kept	Concealment	What it means
Radiant	50%	Obvious	Searing light partially blinds you. You see silhouettes and motion, little detail. Vision Range −50%.
Bright	100%	Obvious	Normal lighting. Vision Range is not affected.
Dim	75%	Faint	Lower than typical lighting that obscures fine details. Vision Range −25%.
Shaded	50%	Veiled	Gloomy. Shadows fill the area. You see silhouettes and motion, little detail. Vision Range −50%.
Dark	0%	Hidden	Total darkness. You cannot see silhouettes, motion or detail. Inflicts Blind.

Concealment levels
Level	Threshold	What it means
Obvious	None	Completely noticeable. No roll needed to detect.
Faint	Novice / Easy	Lightly concealed, easily detected by most.
Veiled	Standard / Challenging	Reasonably concealed. An observant person can find it.
Hidden	Tough / Expert	Completely concealed. Found only with a Study check made with Stagger. Cannot be hit by single-target attacks.
Invisible	None	Cannot be detected at all, even in Sense Range, unless an Ability overrides it. Other senses still work.

Biome Types
Biome	Description
Aquatic	Largely water, such as lakes and oceans.
Coastal	Where land meets ocean: cliffs, beaches and dunes.
Desert	Arid, with low rainfall, extreme temperatures and high wind.
Forest	Dense trees and shrubbery, each with their own ecosystems and weather.
Island	A small piece of land surrounded by water: rough seas, strong winds and storms.
Mountain	Steep slopes, high peaks and uneven rock. Higher means more extreme.
Plains	A large flat area with very few elevation changes.
Swamp	Permanently saturated with water, with trees and other woody plants.
Tundra	Frigid temperatures, little rain, long dark winters, short cool summers.
Underground	Below the surface, such as caverns: high humidity and limited airflow.
Urban	Highly populated regions with buildings and other amenities.

Threat Levels
Threat	Description
Low	Little to no danger. No specialised Equipment or Abilities needed.
Moderate	Some threats and hazards. Basic Equipment or Abilities are required.
High	Noticeable threats and hazards. Intermediate Equipment or Abilities are required.
Deadly	Many threats and hazards. Specialist Equipment or Abilities are required.

Hazard types
Type	Description
Biochemical	Substances that harm through inhalation, ingestion, skin contact or assault on the senses, plus disease-causing organisms.
Elemental	Harsh weather, traps and other elemental-based abilities.
Physical	Direct bodily trauma, commonly from blunt and sharp objects or self-neglect.

Hazard Severity depends on the Persona’s level. Each cell shows damage dice, the number of Effects and the Threshold to resist.

Hazard Severity by level
Levels	Low	Medium	High
1-4	1d4, 0 Effects, TH 6	2d4, 1 Effects, TH 8	3d4, 2 Effects, TH 10
5-8	2d4, 1 Effects, TH 10	3d4, 2 Effects, TH 12	4d4, 3 Effects, TH 14
9-12	3d4, 2 Effects, TH 14	4d4, 3 Effects, TH 16	5d4, 4 Effects, TH 18
13-16	4d4, 3 Effects, TH 18	5d4, 4 Effects, TH 20	6d4, 5 Effects, TH 22
17-20	5d4, 4 Effects, TH 22	6d4, 6 Effects, TH 24	7d4, 7 Effects, TH 26

Survival Rules apply in High and Deadly biomes.

Survival Rules
Area	What changes
Provisions	Food, water, medical supplies, materials and shelter are scarce. A Study or Track check finds limited resources (higher TH than usual), or buy and trade at higher prices.
Injuries	More common. A Study or Track check can find limited medical resources (higher TH). Medics are rare and charge hefty fees or favours.
Hazards	More frequent and deadlier, harder to detect (higher TH) and harder to avoid and disarm, dealing more damage and harsher Effects.
Trait Checks	Generally harder to pass, with more punishing consequences for failure.
Resilience	Some damage types are more or less effective, imposing Exposed or Fortified, typically from the environment.
Vendors	Less common with limited stock. Higher prices, and they pay less for items you sell.
Social Phase	More strained. Foes are less willing to talk and more likely to betray you.
Survey Phase	Harder, with reduced Sense Ranges and Motion. Extreme weather can make areas impossible without specialised gear.
Skirmish Phase	More difficult and frequent. Special enemies are likely, and wildlife is more hostile.
Sentry Phase	More likely to be interrupted. Full Rest is much harder to come by, with heavier reliance on Brief and Light Rests.
