**This has been tested**
Ok I discovered this using Epic flight form but i'm around 90% sure it works with everything else.
Step 1. Go up a reasonable amount into the sky to the point where you will fall for 2 seconds
Step 2. Make a macro that says
/logout
/console logout
Step 3. Put the macro on your action bar , then start falling and click it
Step 4. When you log back in you should start falling to the ground but after you land you'll have slowfall.
Have fun with this (somehow) also I found this completely by myself so that means no copypasta :wave:
