So basically there are 9 seal scroll fragments that I haven't been able to synthesize for a while now. The below screenshots show the ones that i can synth (with the purple names) and the ones that i cannot (with the white names) and descriptions for each. Edit: Also I'm level 105 and it's been at 9 for a long time i.e. i can't synthesize them because i haven't gotten any more of these 9 frags. The seal scroll frags I have been getting are of the purple variety, regardless of where I get them from.
