Stealth

Stealth covers moving silently and remaining hidden from detection. It is governed by Dexterity.

When to roll: The DM calls for a Stealth check when a character attempts to hide or move without being noticed.

Hiding rules:

• You can attempt to hide when you are heavily obscured or behind cover
• When hidden, your location is unknown to enemies; they must guess where you are
• An unseen attacker has advantage on attack rolls against targets that can't see them
• You give away your location when you make an attack, whether it hits or misses, unless a special ability lets you stay hidden

Contested checks: Stealth is contested by the passive Perception (or active Perception check) of creatures trying to detect you.

Armor: Wearing medium or heavy armor may impose disadvantage on Stealth checks (varies by armor type).

Group Stealth: When the group attempts to move stealthily, the DM may call for a group check — the group succeeds if at least half the characters succeed.
