Step 1 : Use leeches to get your SHP very low (3-10 SHP , depending on what leeches you have)
Step 2 : Keep your hunger under 8000%
Step 3 : Keep 1-2 leeches in your inventory when going out
If you get attacked by a player just put a leech on yourself and after about 1 min 20 seconds you will get KO
* Having some armor when going out can help
* Can aggro an animal to get yourself KO too (preferably which does not execute)
