W.I.P

Basic idea: A chamber to infuse alchemical power into you and your bound armor temporarily. Lasts a long time(Half an hour?), and effects can be stacked with each other.
A base failure chance(10%?) that raises with every effect. If the armor is removed prematurely(Before the effects end) a large burst of alchemical power is unleashed around the wearer.

I'm thinking all imbuements can buff(Or lower) your HP(Using the item aspect mechanic of vanilla) if you are in set circumstances.

Incendium:

Positive outcome:

	Live in the Fire: Boosts the players max HP if in a "Warm" or "Hot" biomes(Boosts it higher if in the nether). Lowers it if in a cold and damp biomes, or while in water.

	Burning stair: After gazing at an entity for a few seconds, it is set alight.

	Blazing Blood: Free fire resistance, and anything that hurts you is set alight.

	Inferno healing: Standing in lava(Perhaps also fire) gives regen one.

Negative outcome:

	Overheated: If in a warm biome while under the sky during the day, you are set on fire.

	Die in the Flame: If in water, the rain, a humid or a cold biome, you start taking damage slowly over time.

	Fire feet: Running causes the ground at your feet to be set alight.

Aether:

Positive outcome:

	At one with the breeze: HP boost based on your Y value. Normal HP at Y64, lower if below this and higher if above.

	Aura of air: Items are pulled to you from a longer distance then normal

	Cushion of wind: You fall slower then normal

	Bridge of the breeze: Holding shift creates spectral blocks under you.

Negative outcome:

		Light as a feather: You are knocked back farther then normal.

		Move with the breeze: While under the sky, you can be pushed a few blocks in random directions. The sky part is not needed in the nether, and are pushed even farther by the currents of the hot air caused by lava.

		Musty air: You can not regenerate HP while not under the sky.
