Relic Weapon Step 1

[Riviera_Kruesvir]

Obtain the quest Weaponsmith of Legend from an NPC near Waking Sands north of Horizon.  He'll have you go talk to Rowena, then talk to Gerolt in Fallgourd Float North Shroud.

1.  Obtain the weapon it asks you for in the journal with two materias meld to it, please note to pick what class you want your relic weapon for as you'll need to be in the class throughout the step to get your relic.
2.  Talk to Gerolt, he'll ask you to slay a Dhorna Chimera located north corner of Camp Dragonhead in Coerthas.  Its an 8 person raid, and be in the class you want to do the relic weapon for.
3.  Talk to Gerolt, who'll then have you talk to Rowena then request a glyph in Amdepor Keep NM, a four person dungeon.
4.  Talk to Gerolt again, you'll get an unfinished relic weapon, then you'll need to slay a number of beastmen or creature with the weapon equipped, afterwards he'll have you slay a Hydra, an 8 person raid like the Chimera situation.  Again, you need to run the raid as the class you have the unfinished relic weapon for to gain the item.
5.  Talk to Gerolt once again, he'll have you get 3 items from Ifrit, Garuda and Titan Hard Mode.  Each item is dropped after the raid so no worries about multiple runs, as for the order it may say on the journal.  After that, you'll need to get Ratz-at-Han Quenching Oil that cost 30 poetics from Auriana in Mor Dhona.  Turn in the items and Gerolt will give you the relic weapon.

Congratulations.
