Lots of stuff needs to be done regarding familiars

All familiars as a whole:

• Familiar names only appear when successfully completing the proper ritual on a desired mob to become a familiar. Even though you can rename it to something else afterwards.
• Mobs that extend EntityFamiliar are all valid, and can be used for said ritual. However, they must be tamed first before said ritual can be done.
• De-derp some of their AI
• The physical body of a familiar should not be immortal, but a ritual can call back all of your familiars if one or more dies. However, their death can cause severe damage or even death to you, and nothing can protect you from it. Furthermore, animals that can become familiars that are merely just tamed should not be immortal and their death should have no affect on the player.

Snakes

• Snakes should allow a player to deal more damage to spirits as a whole (including demons), and also get better deals with them, and lessen the chance of their ire.
• Allows the player to see invisible mobs and players

Owls

• Owls should allow for better navigation via teleportation, brooms, and elytra
• Owls can carry items to an individual and return, provided you use the appropriate taglock

Ravens

• Spells cast by a player are more efficient, have more of an effect, and cost less to cast
• Players have more ME if they have a raven familiar

Toads

• Increases the potency of all brews created by said player by default
• Allows the player to create a brew that allows them to force a target to hop out of control and suffer from severe nausea

Familiar functions are 100% in the docs now.
