Magic Forums

Alright, just to begin, I'm not sure I posted this in the correct section, so if I didn't, I'd appreciate to know where it should be posted.

Alright then. Recently I heard about this stone that medieval witches would use to cast spells, but I have no idea what it was called, so that's why I'm posting this.

I heard that it was used in black magick when witches would cast spells, and it was designed to amplify their intent, or something like that, when they would repeat it over and over. However, I was only able to read a small paragraph on the item, so I'll try my best to describe it.

This is all I really know:
The tools were man-made stones with equidistant holes in them, usually in multiples of three. And a cord or pebble would be passed through the holes in patterns of three while the witches cast their spells.

So yeah, if anybody knows what this is called, please let me know. Thanks!

P.S. I'm not getting involved in black magick, for anybody who may think that. I'm just looking to expand my knowledge.
