Curse

Curse is one of the stats in Vampire Survivors. It buffs enemy speed, health, and spawn frequency and quantity.
The player has 100% base Curse before modifications. The Curse in the stat panel is given as the difference to the base Curse, meaning that Curse stat of +30% equals to 130% total Curse, for example. Curse modifications from character bonuses, PowerUps and items stack additively.
There is no upper limit to how much Curse the player may have.
==Effects==
Curse increases the frequency and quantity of enemy waves, as well as increase their speed and health by the percentage of Curse. The multipliers to health, speed and enemy minimum stack multiplicatively with other effects of the same kind.
The new spawn interval with any amount of Curse can be calculated as follows:
:effectiveSpawnInterval = \frac{spawnInterval}{totalCurse}
When Curse is gained during a run, the health multiplier effect is immediately applied to all newly spawned enemies. All other effects are applied at the start of the next minute.
Curse also affects:
