Sneak is an Agility perk in Fallout 4.
Effects[]
Taking ranks of this perk decreases the chance to be detected when sneaking. Higher ranks enhance the decreased chance as well as negate the player character's ability to activate enemy traps and mines, negate the effect of sprinting on stealth, and grant the ability to become undetected by going into stealth when enemies are far away.
Ranks[]
| Rank | Requirements | Description | Form ID |
|---|---|---|---|
| 1 | AGI 3 | Become whisper, become shadow. You are 20% harder to detect while sneaking. | 0004C935 |
| 2 | AGI 3, LVL 5 | You are now 30% harder to detect while sneaking, and no longer trigger floor-based traps. | 000B9882 |
| 3 | AGI 3, LVL 12 | You are now 40% harder to detect while sneaking, and no longer trigger enemy mines. | 000B9883 |
| 4 | AGI 3, LVL 23 | You are now 50% harder to detect while sneaking, and running no longer adversely affects stealth. | 000B9884 |
| 5 | AGI 3, LVL 38 | Engaging stealth causes distant enemies to lose you. | 000B9881 |
Notes[]
- Other bonuses that stack with this perk in helping avoid detection are:
- Agility itself
- Armor with the Cunning legendary effect
- Sneak bobblehead
- U.S. Covert Operations Manual magazines
- Shadowed and Muffled armor mods
- Silencer weapon mods
- Ace Operator perk
- Invisibility such as using a Stealth Boy and/or the Stealth Boy power armor mod.
- Sneak works very well with Ninja and other perks that increase the sneak attack bonus multiplier.
- Rank 2 applies to all non-trigger-tension traps, such as physical tripwires, bathroom scales wired to grenades, and even laser tripwires on walls.
- The trap- and mine-negation bonuses from ranks 2 and 3 also work when not sneaking.
- Rank 4 seems to completely eliminate the effect of footsteps on detection odds. If it is active, then Muffled armor mods are unnecessary and sneaking in power armor becomes much easier.
- Rank 5 bestows an effect similar to that of a Stealth Boy or Chameleon legendary armor effect when entering sneak mode, rendering the player, any equipped weaponry, and the Pip-Boy invisible for approximately one second. Note that this can interfere with aiming using non-scoped weaponry, or seeing the Pip-Boy display properly if brought up during that period of time. Unlike Chameleon armor, the player need not remain still for this effect to work.
- Dogmeat had a unique version of rank 5's effect, but this was removed in patch 1.6.
- All companions have the effects of 4 ranks of Sneak except Curie who is missing all ranks, in both her robot and her synth body (after the completion of Emergent Behavior).
- Certain NPCs are scripted to turn hostile when stealing from them, even if the player was not caught and was hidden.
Behind the scenes[]
The workings of Sneaking in general and the associated perk/skill underwent a steady evolution with each new Bethesda RPG. One difference is how the AI reacts to an undetected opponent. In Fallout 3, everyone knew instantly where the player character was as soon as the fight started. In Skyrim, opponents would search for the player character, but in a non-smart way and simply run to the location that they saw or heard something. In Fallout 4, opponents take evasive maneuvers, run in unpredictable ways, jump from cover to cover and try to take a detour in order to flank the player character.
Bug[]
One might get stuck in crouch position not in stealth mode, unable to either get in standing position or get in stealth mode.
- To return to normal, either get in a power armor or trigger the fusion core attachment animation.
