Diablo – How to prevent friends from joining your game

You will not lose the gear that you have gathered.

You will lose save progress if you start at part 1, you can go back to the quests you already done (In your example 7 to 9).

The way the party system works is that you always enter the game at the level that the host is playing at. If they are further ahead of your character personally you will join them at part 7 (in your example).

When you go back to your own personal game, you can start back at part 1 but it will prompt you to save over your spot in the game. You can continue on from part 9, but you lose out on the story line in between.

What you can do is have your friend join you in your game and help you kill the butcher and jump ahead after that is done.

You can unbind a key by binding it to a different action, and then changing the key for that other action a second time.

Taking your case as an example, we want V to be unbound.

We'll start by opening up the keyboard settings and binding "Toggle Inventory Menu" to V instead of the default I.

You'll see a message at the bottom of the keybindings window stating that "Show Player Health Bars is Now Unbound!"

Now that "Show Player Health Bars" is no longer bound to V, change "Toggle Inventory Menu" back to using I.

Now V is no longer bound to any Diablo 3 function, and is free to use as your push-to-talk key.

These steps are also useful if you find yourself accidentally pressing keys like "show/hide party" and wondering why you can't see anyone on the minimap, and want to make sure you can't accidentally turn it off in the future.
