Is there anyway of obtaining these two Swords WITHOUT doing the Thieves Guild quest? Just seems unfair that 2 of the best Swords are only obtainable through this questline.

I really want these for my Nord because he's Sword+Shield. But I don't want to even go through allllll the BS just to get this far. (About to go to Mercer's Manor).

Yup...

Honestly, IMO the Blades Sword is one of the best when you upgrade it

whats funny is that you dont even have to sneak for the TG you can just barge into a house kill the mercenarys aurding what you are after and take the object.

You can get chillrend. Go round behind Mercers house and go up the stairs, jump on the barrel then onto the roof of the house next to Mercers you can then run along the gate onto Mecers roof. You then weave your way up his roof and drop onto the balcony to access the door into his house. There are videos on YouTube i'd watch one first as its quite tricky. It took me a while to do!

i dont think you can get the nigthingale blade without PC console commands. (or the TG quest of course)

I hate that the Chillrend blade is a leveled reward. i got it when i was like level 25 and now im level 43 and its completely worthless. So i put on all my selling attire and sold it for as much as possible.

If my dawnbreaker sword was broken during combat, is their anyway of getting that weapon again ?

Wait what do you mean broken during combat?

Weapons don't "break" in this game. However if you lost your sword its probably because a draugr deathlord used the disarm shout on you and you happened to drop and loose your weapon (considering you were using dawnbreaker the anti-zombie sword this is probably the case)

Ah ok, yes you are right. Disarmed. Is it actually still laying around and able to be picked up again ? I was aa stage where i was experimenting with some weapons i hadn't used much, with mercer at my side. If i go back will the dawnbreaker be their you think ?
