Just change the order for what you get things in.

Get full Darklight Jewelery first, (4 pieces, you cant have 2 rings of the same kind, sucks for healers.) Then use 900 for the Relic Quest, then anything else you make is a bonus and can be used to slowly get any Darklight pieces that might help. (Strategos will tide you over fine, maybe even save DL pieces for an alt job if you're gonna get AF2 gear with Myth stones)
