Gold

Gold is a currency found in Risk of Rain 2 that the player uses to buy items from Chests, Shrine of Chance, and activating certain Interactibles.

Gold is primarily collected by killing enemies, but there are several Items and Interactibles that can also provide gold.

The following is a complete list of all Items and Interactibles that can be used to obtain gold faster:
 * Barrels
 * Shrine of Blood
 * Shrine of Combat

When the player activates the Teleporter to leave the level, all gold collected on that level will be converted into experience. The gold-to-experience conversion is relatively unfavorable to the survivor and gets worse over time.

Gold Farming Strategies
Items effects and intractables aside, how fast the survivor gains gold is primarily based on monster spawns. The Directors determine the rate, quality, and gold rewards for every enemy that spawns. See the Directors page for more detailed information, but the results are summarized below:

Enemies that are spawned before the survivor first arrives on a stage are worth the least. Counter-intuitively, although enemies spawn fastest during the Teleporter event, Teleporter event enemies are worth significantly less than enemies that spawn before the Teleporter is activated. This is especially true for the Teleporter boss, who will drop hardly any gold. The most valuable and cost-effective naturally-spawned enemies are therefore the ones that spawn around the survivor while the Teleporter is inactive. Unnaturally-spawned enemies (like from a Shrine of Combat) are worth even more than that.

In conclusion, the most optimal gold-farming strategy is to wait to start the Teleporter until your funding goal is fairly close to within reach. Starting the Teleporter too soon means you will have to leave the radius and spend overall longer farming lower-value enemies, while starting the Teleporter too late will result in a surplus of gold.
