Brittle Crown

The Brittle Crown is a new item in Risk of Rain 2. The player has a chance to gain gold anytime they strike an enemy, but they will lose gold whenever they take damage themself. The gold lost when taking damage is proportional to the amount of damage taken.

The chance to gain gold when damaging enemies is affected by the proc coefficient. The amount of gold gained is also affected by the Difficulty Coefficient.

Turrets are affected by the Brittle Crown, but they gain and lose gold independently from the player. Since the Turrets cannot use gold in any way, this makes the Brittle Crown effectively useless for them.

Math
The formula for gold earned is:

C = Amount of Brittle Crowns

D = Difficulty Coefficient

Shrine of Blood
The Brittle Crown has a unique interaction with the Shrine of Blood.


 * The amount of gold earned is not added to the total amount of gold when calculating gold lost.
 * If the player has 100 health, 100 gold, and one Brittle Crown, using the Shrine of Blood for the first time will leave them with 75 gold.
 * Taking 50% damage, they lose 50% of their gold, leaving them with 50 gold. The shrine always gives 50% of the health taken as gold, so they then gain 25 gold.
 * Brittle Crown subtracts gold based on the player's fullCombinedHealth, which is their maximum HP plus their maximum shields. This is the same value that Shrines of Blood use, so as long as the player's fullCombinedHealth is more than two times their current gold, using a Shrine of Blood for the first time will net a profit.
