well im not 100% sure. I tried sneakattacking giants a few times and it didnt work (never tried a dragon) and i think i remeber to have seen it somewhere (in the wiki?). Would suprise me if you can actually sneakattack them oO THATS FOR MEELE ONLY. Im pretty sure you can get sneakattacks with ranged weapons on them. with alchemy smith and enchant with shadow warrior perk. i can insta kill everything.(companions will screw your shadow warrior if they join the fight). i was only wondering if i could still insta kill everything if i switch my ancient shrouded gloves into something else. i did some math and my total dagger sneak damage is 12425 with shrouded gloves. if i take it off i think it goes down to 6k or something. i forgot. can i still instakill everyone with a half crit bonus? in legendary difficulty.
