Sleep Ammo is an Ammo type in Monster Hunter World (MHW); it comes in two levels.


When fired from a Bowgun, Sleep Ammo releases a single projectile which deals Sleep buildup damage to a target.

All levels of Sleep Ammo have the following basic properties:

  • Buildup caused by Sleep Ammo triggers the Sleep Ailment on a Monster, which incapacitates a Monster for about 40 seconds.
  • While Blademaster weapons have a 1/3 chance of causing buildup with each hit, it is guaranteed with each shot of Sleep Ammo. Level 1 does about as much buildup as a Weapon with 400 Sleep damage, while level 2 does about twice as much.
  • Buildup is affected by the Sleep Attack Skill. It is not affected by Attack, and is only affected by Affinity with the Critical Status Skill active. 
  • Raw (physical) Damage of each projectile negligible due to a very low Combo Move multiplier. See Attack Power for more information.
  • Some Bowguns can fire Sleep Ammo in rapid-fire or quick-reload modes.

See the articles for Light Bowgun and Heavy Bowgun for more information on Sleep and other ammo types.
See Bowgun Ammo for a quick list of Bowgun Ammo types.

See Status Effects for more information on Sleep and other Blights and Ailments
