HP drain rate

For health as a gameplay mechanic, see: Health
For regulations surrounding HP drain rate, see: Ranking criteria

HP drain rate (HP) is a beatmap difficulty setting that controls how much health is passively lost to health drain. It also affects how heavily a player is penalized for missing notes and how much health is gained back by accurately hitting hit objects.

HP ranges from 0 to 10, where 10 is the most punishing and 0 is the most lenient.

Mod effects

There are four mods that alter the HP drain rate when activated:

  • Easy: Halves the HP value.
  • Hard Rock: Multiplies the HP value by 1.4, up to a maximum of 10.
  • Double Time: The HP value is not affected, but due to the 50% play speed increase, health drain occurs 50% faster.
  • Half Time: The HP value is not affected, but due to the 25% play speed decrease, health drain occurs 25% slower.
