A sign to burn my halo 😇

You can light halo and buy unhex. When it arrives you can still light it just make sure you're specific in your chant not to remove any positive work that's already done.

Unhex is to remove curses right or is that a necessary step before using halo?

If you feel that, those lines are bad energy or negativity in any way form then you need unhex before halo. Now if you don't then halo will be a good to go.
