Here is the [HOW TO GET THE BLUE CIRCLE] in OSRS
! IMPORTANT - Do this +- 5 minutes before your membership runs out !
- Go into the Soul Wars minigame tutorial.
- Wait X minutes in the Soul Wars tutorial until you think your membership has ran out.
- When your membership has expired, click on "Click here to logout". This will log you out of the game.
- Log back into a non-member world (ex. world 301) with the blue circle underneath your feet.
PS: The blue circle is located in your "beard/jaw slot". From what I know it can only be removed by the Chaos Elemental. The Chaos Elemental will then put a Soul Cape (color: blue) in your inventory. This cape is not tradable and will be lost upon dropping.
Good luck exploiting
