(r) = Reverted Potion
- Bits 0-3 (1, 2, 4 and 8) determine the potion effect. The highest legitimately available is currently 14 decimal = 1110 binary.
- Bits 0-5 (1, 2, 4, 8, 16, 32) determine the potion's name.
- Bits 5 (32) and 6 (64) determine the potion's modifier.
- If bit 5 is true, the potion is a level II potion (or, in some cases, a reverted potion).
- If bit 6 is true, the potion is an extended potion (or, in some cases, a reverted potion).
- Potions with bits 5 and 6 set to true cannot be brewed, but if obtained through commands or other means, will appear and function as level II and/or extended, depending on which modifiers the effect supports.
- Bits 13 and 14 (8192 and 16384) determines whether the potion is a drinkable potion or a splash potion. If bit 13 is true, it's drinkable. If 14 is true, it's a splash potion.
- Potions with bits 13 and 14 set to false cannot be brewed, but if obtained through commands or other means, they will appear and function as drinkable potions.
- Bits 7-12 and 15 are ignored, thus many potions with distinct data values will have the same properties.
