I'm curious as to whether running around killing people with a dagger will raise the sneak skill now, considering how dagger perks are nestled in the sneak perk tree rather than 1-handed.
I'm pretty sure stealth kills(finishers) will increment the sneak skill.
Yeah, I know you had to be moving. Did the faceplant running into the corner way too many times. I could've sworn there was maybe a better chance to skillup if someone was watching you and it successfully put you into stealth though.
I'm pretty sure someone had to be in range of you while sneaking, no?
Yes, you DO have to be within detection range of an NPC to increment the sneak skill while sneaking. Also undetected attacks while sneaking incremented your sneak skill.
