What I meant was are there any locations where big monsters spawn that drop large rift crystals. Also are there any locations for treasure chests that have large rift crystals that can be farmed for maximum output.
Midnight Helix has either a frostwyrm or a gorecyclops, if you get the frostwyrm beat it then clear the area and lay down some rancid bait and a cursed dragon will come and they give a descent amount of RC. If you kill the gorecyclops and do the same it will spawn death who is a bit harder, there are also two tier 3 chests one past the bridge on the first floor where there are a pile of bodies, and a second chest a the top where you get the void key. Both of those chests spawn rift crystals, perfect RC, Bycrystals, and a rare chance of BBI lv3 armor. Just use the godsbane trick to get what you want!!! =)
Note: This is on the second playthrough of BBI when of course when you fight Daimon and he has his second form. Hopefully this helps
I've already taken full advantage of the lvl3 armor chests. What I was thinking was finding all the locations that have those silver and gold knights and farming them because I know they drop insane amounts of crystals.
