Flask of Gold

The Flask of Gold is a flask that increases the number of coins dropped by enemies. While under the influence of a Flask of Gold, melee (and Whip) attacks will inflict enemies with Midas, causing them to drop 10%-50% more coins.

Tips

 * The Flask of Gold also makes your pickaxe and melee weapons provide light, making it a sidegrade to the Shine Potion, since it also improves money drops but requires constant use of your weapons or tools.
 * The Lucky Coin and its upgrades operate independently, and can make hunting and events even more profitable.
 * All enemies and bosses are affected by any melee weapon, including "ranged" weapons such as Boomerangs -- As long as it deals "Melee" damage ( or as long as it is a Whip), it will be applied to it no matter what the attack is. One can tell which ones will apply the effect by the glowing golden sparkles the weapons/projectiles will emit upon use.
 * When using the Flairon, only the Flail applies the buff, but not the bubbles.
 * The total cost of buying the Gold Dust is . So, even with the lowest benefit possible (10%), you will get a return on investment after earning just . Killing a Mimic, the Queen Bee, or any hardmode boss will do, but mass-killing pre-Hardmode bosses may be very profitable, and the Solar Eclipse is ideal.
 * Note that in Expert Mode bosses drop their money inside Treasure Bags, which are not affected by Midas.
