i have the dragon armor the king made and now equipped there is a box that says something is needed i used the letter from the lady but i still cant walk up that path towards the dragon its like there is an invisible barrier there

Hmm, lady close to Ishad gave you letter to put to box, so maybe she wants you to return to tell her you finished it and she will tell you how to turn off barrier. Just speculations.

Have you tried equipping the dragon armor on your lead party member? That's the only suggestion that I can think of at the moment.

Good Luck.

Ive gone back too the lady and equiped the dragon armor the barrier is still up any ideas?
