Vegtam, I've actually come to the conclusion a long time ago that using runes to achieve something good or, conversely, something bad is quite pointless, as they are not (at least based on the information available to us) a direct representation of a specific action or object. They are more like beacons.
And also, the runes were different for each people; some were similar in appearance, but different in meaning, and so on. There was also the Slavic script, in which some runes were very well copied or simply resembled each other for some unknown reason.
In general, I don't know the meaning of most runes, and I've already forgotten the names and even what they look like; I can't reproduce them accurately. I've wanted to study them thoroughly about 10, or even 15 (maybe even 20) times. But first, I didn't have enough material, then I didn't have enough time, then I didn't have enough material again, then I gave up, and so on. Now there's the whole internet, but still...
And the runes have become "overused," or something. Clever people have long since done the same thing with them as they did with "Feng Shui." They've learned to sell it to the masses: if you wear a piece of wood with an unknown picture around your neck, then you are an incredibly spiritually and esoterically advanced person! Boom! 11oneone
This also makes it difficult to find reliable material.
And as far as I remember, anyone could carve runes, anytime, and for any purpose. If you have a collection of runes in a pouch.
I put a rune on my avatar because I wanted to put a rune on it. I opened the list, found the one I liked the most, and put it on; it partially reflects my essence.
