Where to farm Carlotta's materials

Sword Acorus

Grows in the wild and respawns every couple of days; run a Rinascita City route while a boss reward claim is on cooldown.

Platinum Core

Boss drop. Found at Sentry Construct, Averardo Vault (Rinascita).

Claim the reward for 60 Waveplates. Farm the nearby Sword Acorus while waiting for the boss to respawn.

LF Polygon Core

The Polygon Cores drop from Polygon-type enemies; the Synthesizer also converts lower tiers into higher ones.
