Potion of Amplifying

Outline:

The Potion of Amplifying would be used to amplify other effects a player has active. For example a player with haste 1 applied could drink a Potion of Amplifying 1 to get haste 2. The potion also has potential to be dangerous, you might not want to use it when fighting a mob which applies negative effects to the player.

Obtaining:

A Potion of Amplifying can be obtained in a brewing stand by adding a fermented spider eye to a Potion of Nullifying. It can be modified with gunpowder, redstone, glowstone and dragons breath the same way as other potions are.

Uses:

A Potion of Amplifying would apply the Amplifying effect (either 1 or 2) to the player when used. The first level of Amplifying will boost a level 1 non-amplifying effect to a level 2 effect. A level 2 Amplifying effect will do the same as a level 1 but also boost a level 2 non-amplifying effect to a level 3 effect. This would make it possible to apply a bunch of level 3 effects previously not possible to apply in survival.
