For you to be able to get away with using this cheat you will have to start a new campaign and choose the reign of the black king first. Do not change anything from this article or the cheat will not work at all and you don’t want that. So follow the guild lines very carefully and do exactly as it sais in this post.
When the game starts, go to the way point of the cemetery right away and then you must go to the tombs. In the case that a event quest will show like Matriarch’s bones or even the Jar of souls then you will have to recall and go to speak to Deckard Cain. Receive he’s mission to get the skeleton king but then make sure you return to the portal.
Upon returning from the portal all the way back to the tombs, then just abort the game by quitting straight away. After start a new campaign then your done, as simple as that. This will restart you in a new game of defiled crypts but retaining the event quests you gathered along your way. You can keep doing this for as long as you please which is also pretty cool.
Remember to not change anything from this tutorial what so ever as this is the way it works. Doing so may result in failure and wondering what you did wrong when the wrong doing would mean changing something from this article.
