Any easier way to get Savage Aim / Might Materia?

[Gillionaire]

So is there any better way to get savage aim / might materia? I am working on my relic and I am on tier 4 for DET (tier 2 on CRIT) and they run on average 400-500k each. If it was 100% success rate it wouldn't bother me so much. But the thought of tossing 400k into the crapper on a 60% success rate kind of bothers me. I don't have a mess of gil so that would eat up like 1/6 of my savings.

Any advice would help. I know some people spirit bond their own stuff, but isn't that terribly time consuming?

spiritbonding isn't too bad. You can spiritbond a full set of 11 pieces in about 40 minutes.
If you're wearing crafter sets from Mor Dhona on all of your left side, that's a decent chunk of money even if you don't get IVs all the time. then the right side has chance to give you what you need.. But even if you don't, you can always sell it for money.

Besides, you're talking about a relic... the entire thing is "terribly time consuming"
