Notes

  • Other bonuses that stack with this perk in helping avoid detection are;
  • Rank 4 seems to completely eliminate the effect of footsteps on detection odds. If it is active then muffle armor mods are unnecessary.
  • The trap avoiding bonuses from ranks 2 and 3 of this perk also work when not sneaking.
  • All companions have the effects of 4 ranks of Sneak except Curie who is missing all ranks of Stealth in both forms (robot and synth). Dogmeat has a unique rank 5.
  • Sneak works very well with Ninja and other perks that increase the sneak attack bonus multiplier.
