Hex

A hex is a spell in which a witch performs malevolent magic on a target.

Description
Hexes vary from each other, from the procedure, the requirements, and to the effect, although generally, they are similar in nature and purpose--to harm or even kill a target. Hexes are powerful forms of magic because they could conjure creatures or organs out of nowhere. They could also create diseases or outright kill their targets by creating wide slashing wounds.

Procedure
Hexes usually require a medium like hexbags or coins. Each hex and their corresponding hexbags required different ingredients. While some require incantations, others do not. More powerful witches like Astaroth did no require a hexbag to perform a hex on Dean.
