First off, why bother hexing anyone? That just calls for a, war itself.
Next, cursing and hexing are closely related.
Moving on, put up defense lines. Cast a circle, shield, and ask for protection. Magic is not a, toy. It is a tool. A, tool that can harm, or heal.
Here are the two spells i know, that can break a hex/curse.
Break Another Witch's Spell :
*A silver cord, and your magic knife. As well as scissors.
1: Tie a knot on each end of the cord.
2: Visualize the word caster/person
3: Chant the following
*From you to me, this spell i break
This was not right for you to make
Its the path i abruptly end
Back to thee sender this spell i shall send*
Next cut the cord in half, and bury it.
The other one, is freezing a candle with the words 3fold on it, for a week.
