Just read this post and its the funniest thing to see these ideas and "techniques". but ima fill you guys in on the secret of defeating the anvil Boss. as most of you know this is the one boss that very few people are satisfied by its results.
In order to beat the anvil boss follow these steps:
1. while holding the space bar drag in your items and scroll
2. leave the window open for about 5mins, take a piss drink some water, whatever.
3. before you press okay make sure that you have your pinky finger of your left hand in the air.
4. once you have successfully upgraded DO NOT try to upgrade on the same server. logg off and go to your second server and redo steps 1-3.
5. After you have successfully upgraded to your desired lvl, thank me for this secret in game.
