At what point does your sneak skill become "too high" with the use of perks and essentially resets your skill to zero? I want to perk a few points into the first sneak tree item, "Stealth", but I also plan on having 100 sneak at one point. If you can tell me how many perk points are safe and what value the skill experiences problems at it would be appreciated.

at 135 Sneak (100 Sneak, Shrouded Hood, 15% Sneak ring) it still seems to work right for me. I'm wary of raising it any farther though it seems unnecessary to do so.

I only have 3/5 Stealth ranks though. I'm not sure how that affects the equation.

I've heard something like the 4th or 5th rank in the first stealth perk will do it.

I have insane sneak almost every perk and sneaky boots.

I often can sneak right in front. Of a draugr other times they see me and I am surprised how far they are from me when they do. ShadOw warrior works really well at night or in low light dungeons. But once in a low light cave I failed 6 crouch/uncrouch/crouch in a row. I have sneak attacked a dragon but only before combat started.

Hope that helps. I did not have problem overperking sneak myself

I have 100 with all the perks without any gear to enhance sneak. It's working ridiculously well.

I've read pickpocket is bugged when you take the last % increase chance perk though.
