Chance of Obtaining a Drop[edit | edit source]
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]).
Item Drops[edit | edit source]
- For a list of all dropped items see Drops.
Some items are dropped by all monsters (except Meteor Heads) under certain conditions. Those can be found below.

Coin Drops[edit | edit source]
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 100 . 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[edit | edit source]
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 1/1000Verify. Players can easily see the effect when farming for more common loot such as souls.
