Player.dat format/Potion

• •  CustomPotionEffects: The custom potion effects (status effects) this potion or tipped arrow has. A potion getting its effects from this tag will be named "Water Bottle". A tipped arrow will be named "Arrow of Splashing".
    • One of these for each effect.
      •  Id: The numeric ID of the effect.
      •  Amplifier: The amplifier of the effect, with level I having value 0. Negative levels are discussed here. Optional, and defaults to level I.
      •  Duration: The duration of the effect; 8 duration = 1 tick. Values 0 or lower are treated as 1. Optional, and defaults to 1 tick.
      •  Ambient: 1 or 0 (true/false) - whether or not this is an effect provided by a beacon and therefore should be less intrusive on the screen. Optional, and defaults to false. Due to a bug, it has no effect on splash potions.
      •  ShowParticles: 1 or 0 (true/false) - whether or not this effect produces particles. Optional, and defaults to true. Due to a bug, it has no effect on splash potions.
  •  Potion ^{(since 15w31a)}: The name of the default potion effect. This name differs from the status effect name. For example, the value for an "Instant Health II" potion is "minecraft:strong_healing". A potion or tipped arrow getting its effects from this tag will be named with the proper effect.
