Diablo – What determines revive time

No, they don't die. If they go to 0 health, they disappear from the battle and reappear sometime later (even if the same fight is still going on).

It was easiest to test this with the skeleton king. My templar "died" a couple of times and came back 30 seconds or something like that later (Although that number is just an estimate, I haven't measured).

Hit T to teleport to town, then logout, and it will log you out instantly

Logging out is instant if you have the In-Town buff, and the Teleport animation is faster than the logout timer (4 seconds vs 10 seconds)

In addition, you can do other things while casting, such as looking through your inventory, or at your skills, or admiring your character and/or surroundings (which is what I usually do when teleporting). This gives you the illusion that you are not sitting around doing nothing while you're waiting to logout, which reduces the aggravation caused by it :)

As far as I know, there is no way to disable the logout timer in unsafe places for the reasons tater596 mentioned
