NPC drops

Most enemies drop coins when they are killed, and many also have a chance of dropping various items.

Chance of Obtaining a Drop

To determine the chance for at least one specific item to drop for a given number of mobs with the same chance of dropping said item, use the equation:

• 1-(1-([drop chance]))^([number of mobs]).
  

To find how many mobs are needed to obtain a certain percent chance it has dropped at least once, use:

• ln(1-[%chance in decimal (70% = .7 etc...)])/ln(1-[drop chance]).

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 1. 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.

Template:Console icon 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.
