Nice clear! Did you save Wamdus S3 until the 2nd half just for the 12 skill omen or was there another reason for not using it earlier? Also, not sure if it was shown at some point and I missed it but what are your sub summons? I'm guessing something like Gabriel + Grande?
The staff on the bottom-left and the harp on the bottom right. I forget the name of the first but its Sophia's recruitment weapon and the harp is Ophelia.
