As this method hasn't been found in my searches (i hope) I got bored and decided to share something I knew for a while.
As it is NOT an exploit in my opinion, and even if it was, I wouldn't put it there because "NO USELESS" is allowed. So I put it here where I think it should belong.
Here we goes:
Materials Needed:
Brazier of Dancing Flames
Shadow Crystal Focusing Lenses or Shadow Jade Focusing Lenses or Dark Jade Focusing Lenses
The Instructions:
1. Drop the Brazier of Dancing Flames. Drop it down on the ground. Don't delete it. Use it.
2. Target someone or and NPC or anything that can have a beam channeled at them.
3. Use your focusing lenses, then target the Dancing Flames.
4. DON'T MOVE. Type /dance in the chatbox and you should look like the picture above the instructions.
