You have to do them in the exact oder. You can't beat them all 3 and go to Herold and get your Relict.
When you do a Relict for the 2nd to 9th time you have to:
1) Find unfinished weapon
2) Craft class weapon and insert Materia (or spend GIL to buy it)
3) Fight Chimera
4) Go to Ampador (classic 2.0 version, not Historical Ampador)
5) Fight 24 mobs with unfinished weapon
6) Fight Hydra
7) Fight Ifrit
8) Fight Garuda
9) Fight Titan
10) Buy Bottle of Radz-at-Han Quenching Oil for Myth and return to Gerolt (buying can be done in advance at any stage)
No chance to skip anything on this list or do things in advance. You HAVE to do everything when the quests ask you to do it.
