• Drop from quests and side-scrolling scenes on Merkmal Island. Notable quests:
  • Chapter 80 Story: An Unfamiliar Sky - Episode 4 (23 AP) - 0-1 per quest, typically dropped by Rare Monster Scrap Salamander. Very low drop rate on regular enemies.
  • Chapter 80 Quest: Stocking Up for Winter (23 AP) - 0-1 per quest. Also drops 0-1 Merkmal Fig and 0-2 Corroded Cartridge. (Recommended with Kaguya (Summon) and BountyItem drop rate is boosted
    )
  • Chapter 81 Story: King of the Outlaws - Episode 1 (23 AP) - Belle Sylphid required for Rare Monster appearances, but has the fastest clear time (only 1 battle).

    . Kaguya (Summon) (or another drop-rate-boosting summon) recommended.
  • Chapter 81 Quest: The Mysterious Room (50 AP) - 1-3 per quest, but poor drop rate on Merkmal Fig and does not dropVerification needed. Corroded Cartridge. Run only if you're desperate for Bastion Blocks. Quest is unlocked after clearing Chapter 85 Story: Pholia the Maiden.
