can the relic weapon quest be only done once?

Wad just curious ifbit was a one time thing. Say you got relic for paladim, can you not get for warrior now?

you can get a relic for all the classes

You can run it once for each class. If you get rid by accident or on purpose of any of the relic weapons you can re-purchase them from the Calamity Salvage NPC.

The quest for new jobs will start at Gerolt.
