Snuck up on a Frost Dragon in Skyrim, and killed it in 2 hits with a dagger. My character's life is now complete.
I heard sneaking in the game makes it broken. Personally, I just like going around the land searching for dragons and just taking them out with Arrows, no magic.
Sneak arrows are just as broken. It's what I play as.
Actually most everything in that game is broken once you reach a certain level. But it's a fucking single player RPG so who gives a shit what's unbalanced for players and what's not.
I don't do any sneaking. I just use regular brute force to take down dragons.
