NPC drops

Most monsters will drop coins when they are killed, and many also have a chance of dropping items as well.

Soul Drops
When in the Underground Hallow, all enemies have a 1/5 chance to drop Soul of Light, and Soul of Night when killed in the Underground Corruption or Underground Crimson. Even enemies spawned from other areas will drop souls based on the current area. For example, a Chaos Elemental in the Deep Corruption will drop a Soul of Night, not a Soul of Light.

Summon Drops
Once you enter hardmode all enemies have 0.1% chance to drop a Mechanical Eye, Mechanical Worm or a Mechanical Skull if you have not yet defeated the boss summoned by that item. If you wait some time before you start killing bosses this can potentially give you multiple free summoning items.

Biome Key Mold Drops
When in hardmode every enemy has a 0.04% (1 in 2500) chance of dropping a Biome Key Mold. The type of Biome Key Mold that is dropped depends on the biome you are currently in (Jungle, Corruption, Crimson, Hallow or Snow)

Christmas Drops
During the Christmas holiday season (December 15th-31st) all enemies have 7.69% chance (1 in 13) to drop a Present.

Halloween Drops
During halloween all weak enemies (<20 defense, <40 damage and <5 silver coins loot) will have a 1 in 2000 chance of dropping a Bloody Machete. Under the same conditions they also have a 1 in 2000 chance of dropping Bladed Glove. Furthermore all enemies have a 1 in 80 chance of dropping a Goodie Bag.

KO Cannon
During a blood moon in hardmode all enemies have 0.1% chance of dropping KO Cannon.

Coin Drops
Most monsters will typically drop a few stacks of coins after dying. Monsters that drop a large number of coins have a higher chance of dropping multiple stacks.

The total amount of money dropped is calculated using a "base value", which depends on the monster. A Skeleton for example, has a "base value" of. The exact amount of money dropped is this number multiplied by 80-120%.

After the amount of money is determined, there are then a few chances for the number to be increased.


 * 20% chance of increasing by 5-10%
 * 10% chance of increasing by 10-20%
 * 6.67% chance of increasing by 15-30%
 * 5% chance of increasing by 20-40%

These increases are not mutually exclusive, and a monster may have its money increased several times. It is possible to get all increases at once, as each one is rolled individually. The average amount dropped, therefore, is 119.5% of the "base" value. It is possible to get it even more increased by the Lucky Coin.

Double Loot
Console versions of the game give players a chance to have double the loot drop from any enemy. The exact chance of this happening is unknown. Players can easily see the effect when farming for more common loot such as souls.
