Familiars

The familiar system would function like this:

-The Enchantment table would have a special section for Enchantments and Familiars. Switch to the latter.

-You'd need two items: A Totem of Undying and a Soul Fragment.

-You can get soul fragments by "feeding" a creature a Nether Star. After killing a creature that was fed you'd get their soul fragment.

-Placing both in their slots, plus some XP, would get you a familiar.

-Each familiar will get you a ever-lasting special effect. What effect a familiar gives is different for each one. During this period the beacon (and similar buffers) won't work. One can have only a single familiar "created" at once, meaning another can be made at the cost of the previous dying.

-If you were to die the familiar will revive you, which will cause it to vanish.

-Familiars require sustenance every once in a while. Their diet consists of Glistering Melons, Golden Carrots, Golden Apples and Bottles Of Enchanting.
