Okay so for those who know this quest, you need to get the House of Ballads Armor set to get into Castle Windermere. The only way to get this armor is via this quest. There is an option to dispel the curse on Sir Airmer which with a Dispel level of 4+ you can easily do. I decided to choose this option instead of fighting him. Unfortunately he gives me half of the armor and leaves, leaving Sir Creth there on his own still under the spell. There is no option to dispel Sir Creth and I am unable to kill him.
Thus my game cannot continue with this quest line stopping me from finishing it for the achievement. Now I know I can just use a gamesave to get the achievement but I want to finish off this quest myself. I can also start a new game yes but I'd rather not if I can help it. Without the rest of the armor I cannot get in. Anyone know of a solution to fix this problem seeing as the only help I can find on google is on the forums.reckoning.amalur.com but it seems as if the site has been closed. I do not have another save before this quest as my Auto-Save decided to save right after I made the choice of dispelling Sir Airmer and I didn't make a separate save either (yes I was dumb but I was not expecting my game to break) so I am screwed. I will of course continue my game to finish the rest of it but this 1 quest will be sitting there and I'll have half the Ballads armor set with no chance of getting the rest unless anyone has a save just before this quest so I can finish it off legit or somebody has a solution to fix this.
