Farm Felicity for Moonstones and the Quasar

Felicity’s arena and the treasure room behind it in Titan Robot Production Plant.

Before you go

Advance the campaign to Titan Robot Production Plant and the Felicity encounter.
Bring a boss-ready loadout and ammunition for the fight.
Leave room for chest and boss drops; keep Moonstones available if you plan to open a Moonstone Chest.

Travel through Titan Robot Production Plant to Felicity’s arena.
Defeat Felicity and inspect the drops for Moonstones and the Quasar.
Collect useful gear before leaving the arena.
Proceed into the treasure room behind the boss area.
Open the available chests, including the Moonstone Chest if you can pay its cost.
Compare the loot with your current equipment and collect only what you want to keep.
Save and quit, reload, and return to the area to repeat the boss-and-room loop.

Check both the arena and the reward room; stopping after the boss misses the chest part of the route.
Keep the Moonstone Chest in mind when budgeting currency, since this route can use stones as well as yield them.

Repeatable by resetting and returning to the encounter. Felicity’s Quasar and Moonstone drops are chances; chest contents can vary.

Leaving after the kill without visiting the room skips its extra loot opportunities; continue past the arena.
Arriving without Moonstones while expecting to open the Moonstone Chest can frustrate the run; check your balance first.
Assuming the Quasar drops every time confuses a dedicated chance with a guaranteed reward; repeat only while the target is worthwhile.

Stop when the Quasar variant suits your build, your Moonstone reserve is sufficient, or the route no longer beats your other priorities.
