unlike arcarum which ticket is gated, you can spam raids to enable you to do more expeditions. fast expedition is recommended for fast clear, as the drops arent significant. 3rd/boss node, as arcarum works, cant be skipped, so do check out for diomorphodon (eyeballs), if you clear them you can spawn cybele (equivalent to fragment farm). cybele nets a nice amount of stones (but not nice enough to justify not skipping regular nodes).
not confirmed: goliath. idk what they do, the drop sucks and doesnt seem to have anything to do with cybele spawning.
