Dark Sea Witchcraft
Many sea witches forget that the ocean is a dark, dangerous place, filled with deadly traps and monsters. This post is a collection of ideas on blending dark witchcraft with sea magick. (Note: I, along with many others, do not believe in the threefold law, so please keep your personal ethics to yourself)
Seashells are great for curses, as they can be broken into shards and put in a curse bottle. Research certain shell correspondences if you want a very specific curse.
Black sand can be mixed with black salt (or used by itself) for protective or cursing magick.
Saltwater gathered on the night of a dark moon makes the water even more potent for dark witchcraft.
Fish or turtle bones can be used in curse bottles or for divination. (Please only use bones that you find without actually hurting an animal. If you do sacrifice an animal, donāt be wasteful and please be humane. And definitely donāt sacrifice anything endangered!)
Shark teeth can be used for curses to cause fear in someone, or even bring real harm to them if used that way.
If you think on a broader scale, you can harness the power of the entire sea. Hurricanes and things like that are incredibly powerful, and are aspects of the sea. They kill many, many people, so I donāt recommend a hurricane curse, as they arenāt specific to who they harm.
