I'd love to see an uncommon NPC that dropped crimson amplifiers for high level players. These were incredibly easy to get at lower levels but once you loose the Crimson Overlords, you're left relying on Flamehawks to generate them for you, and that means a whole lot of NPC'ing.

Failing that, it'd be cool to get a Theory Lab blueprint that allows for the conversion of crimson artifacts, like combining 10 Obelisks for an Ancient Crystal or 20 for an Amplifier.

Flamehawks should be 50% Obelisk / 30% Amplifier / 10% Foci / 10% No Drop.

+1 though .. since foci are arti drops I would think 50 30 10 10 Ob/Foci/amp/no would be more balanced.

Even though I'm not there yet, it would be nice when I get there to have a NPC that replaces it.
