The brazier in question
First you need to get under the Shrine itself
There are many ways to do it and they can be found with a little googling / searching OwnedCore but here is one example from Decilicus (Under Shrine of Two Moons)
Next you want to position yourself exactly as shown in these pictures (The tiles, pillars and trees are your friends)
Then pop your Bottled Tornado (Assuming you have one but as you are browsing OwnedCore you should have it already. If not then go get it!)
And the result
Now bask in the amazement of the people who actually notice you inside the flame and let your e-peen stand up in glory
Sadly you can only stand on the braziers as you will fall through the floor and the statue.
