Converts enemies killed by the socketed card into coins. Every kill generates currency, enabling significant coin accumulation throughout a run.

• Effect: Earn coins on kill
• Type: Economy Gem (Superior)
• Stacking: Multiple copies increase coins generated per kill

• AoE / trash-clear cards (Whip, Bone, Knife): Mass-kill trash enemies to earn coins in bulk
• High-Amount projectile cards: Multiple projectiles kill multiple enemies per play
• Return Gem cards: Spam the same card every turn to continuously farm coin from kills

• Greed powerup: Multiplies the base coin output from Midas kills
• Steal Gem: On-kill coins (Midas) + on-play coins + additional kill coins (Steal) = triple economy
• Gallo Crawler: His coin bonus passive stacks multiplicatively with Midas

One of the most important economy gems in the game. Accelerating early Blacksmith upgrades, Jeweler curation, and Power Up stacking from coin income dramatically improves overall run quality.
