“ Perception represents character's ability to discern objects from far away as well as to notice hidden things in their vicinity. It helps the character to use ranged weapons more effectively, as well as detect hidden objects, passages and creatures. ”

— In-game description

Details

Perception determines your character's overall awareness and effectiveness with ranged weapons. It also affects your character's chance to detect hidden passages, objects or stealthed creatures and NPCs. It does not increase your vision or visible range. Perception does not directly affect your chance to hit, but rather increases your ranged weapon skills, which in turn increases your chance to hit with ranged weapons. Melee weapon hit rate is unchanged but increased with melee skill (through strength or dexterity). No items require perception to be used or equipped.

High perception score is important for characters who wish to use ranged weapons or find traps, stealthed enemies and secrets.

Directly affected skills

Other effects

  • Detection
  • Finding secrets (uses perception score instead of detection)

Tilemarker Perception.png

Discovering secret areas is based on Perception score alone, unlike detecting traps and stealthed characters, which is based on Detection. Discovering some secrets requires prior knowledge instead of Perception score.

In addition to secrets, Underrail: Expedition expansion added visible in-world Perception checks similar to Strength, Dexterity and Agility checks.
