So, I killed the Demon Walls on my first time through. However, I did not see any treasure chest containing that mythical Demonsbane. I just kind of said 'forget it' and finished up the dungeon and moved on with the game. If I go back there anytime soon, will the Demonsbane be there, or is it as good as gone?

also, 10 hit quickening chains are lovely. <3
