So, fellow players, we are hoping that there are some amongst you that have played this sort of sneaky, non-combat type that might have some helpful hints or suggestions for Tzirra. We are open to roleplay suggestions, tactics, perk choice advice... but magic and shouts are not an option.
I did Goldenglow without fighting by using arrows to distract guards. If you shoot at a wall, guards will move to wherever they hear it hit - but they'll pause and very shortly after start looking around semi-randomly. The trick is to stealth as quickly as you can to wherever you want to go in those precious couple of seconds that they're distracted.
If you don't like the idea of quicksaving, you can first get an idea of how much time you'll have by finding two safe spots far from your test subjects, firing into a wall from one spot, quickly stealthing to the other, and watching the guards' behavior. Third-person view helps with this, as it lets you "peek" around corners.
Fair warning, though - "normal" dungeons, skeevers, and random encounters might still be tricky without a companion...
