i just started chapter six i've been carrying around the human flesh waiting to make the armor. should i go back and get the blood from the silver dragon in the underdark? i don't think she's there anymore since she escorted me out...

could someone tell me if it's worth it to go back to a previous save, so i can get her blood to make the armor? (ie. what exactly is the armor once it's finished?)

thanks.

Human Flesh +5
Made from human skin and treated with the blood of a noble dragon, this armor emits the stench of bitter death. The malevolent armor can only be used by a truly evil person.

but isnt the dragon the only way out of underdark,

No, you can just bugger off out the exit in the kuo-toan dungeon.
I've said it a few times, the flesh armour is very much mediocre compared to almost every other type of armour you should have collected by the time you get it.

Dragons give a lot of XP
and making that armor too
