It works I only use the sigil part of it. Tho once I start studing magick once agine then I shall pick up whare I left off. Right know I am just doing a lot of energy work. So that is my like. No disslike (burn and get rid of karma).
I adhere to Elder Futhark when it comes to runes, so I'm sure we're not on the same page when it comes to Sowilo.
Chaotic magick is actually a completely different magickal practice. I know nothing about dragon magick, not sure I fully subscribe to all that, but I'm pretty sure summoning a chaotic dragon doesn't involve the practice of chaotic magick. I'm sure the two arts could be combined though.
Sigils are great practice, for the most part. I've really gotten into the incantations though. It's a little more risky, but SO effective!
Have you ever meddled with the incantations?
