Fortify Sneak is both an Alchemical Effect (found on certain ingredients) and an enchantment effect in The Elder Scrolls V: Skyrim. Potions/Enchanted armor with this effect may be created at an Alchemy Labs/Enchanting Table or purchased from alchemist merchants/Blacksmiths.
Potions with Fortify Sneak increase the target's Sneak Skill by making the target harder to detect for a certain length of time. The strength of the effect is determined by the Alchemy Skill of the alchemist that brewed the potion.

- If you have fortify sneak enchants under 'active effects' that acumulate to over an extra 100%, every percent over 100 will cause it to reverse making you less stealthy. e.g: if you have a fortify sneak effects cumulated to 150%, your sneak effectiveness will be of 50% (confirmed on xbox 360)
- this may also occur with a few other select skills such as: lockpicking; pickpocket and speech (speech unconfirmed) (also unconfirmed if the issue is fixed with a patch)
