Discount is a statistic representing the ability to reduce the cost of towers and/or upgrades. Discounts can even make upgrades and towers become free. Most sources of discounts require a tower to be within range to gain the benefit. Paragon upgrades are immune to discounts from all sources, including map-specific gimmicks.

The new cost after discount depends on the game's rounding system.
