Gives a reason to farm the open world, and provides a good challenge for rare items/relic weapons etc. I found the BCNM's difficult, but exciting, and something to shoot for, and since you needed seals/orbs to enter it kept people from just blowing through the content. Basically a RNG on top of an RNG, but the drop rates were much better than atma.

Personally I'd much rather follow this system to upgrade my relic than grinding fates for days with zero progress.

Thoughts?
