Relic Weapon Disgarded

[Youkulm]

I don't remember doing it but apparently, i tossed two recollection relics. Is there any way to obtain these again without doing the whole step line again?

You can only obtain replicas. To continue / finish the relic you need the relic ( so if you're looking to finish the relic you gotta start over ). The replicas are at NPCs near each relic quest NPC, depends on the relic.
