Potion/Before 1.9

(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.
 * If bit 5 (32) is true, the potion is a level II potion (or, in some cases, a reverted potion).
 * If bit 6 (64) 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.
 * 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.
 * Bits 7-12 and 15 are ignored, so many potions with distinct data values will have the same properties.
