"Normal difficulty"

Way Points.
All of the WayPoints (WP's) must be found and activated.

Town portal and Identify scrolls.
No scrolls can be bought in town. You can use only those you find in a game. You can buy tomes of Town Portal and of Idenify only 1 time per all MC game - in town, after completing Act One. Though you can't buy any scrolls to fill them up.

Remember - the only way to indentify item is by a scroll you find. No Cain help is allowed.

Town.
You can't enter a town till the end of an act. You can complete "town required" quests only after a full accomplishment of the present act.

You can pass through the Lut-Golein in Act Two few times since otherwise it is impossible to go further. However, you can't do anything in a town (buy, gamble, sell, repair, use stash, ressurect mercs, Cain identify).

After each act you can enter a town and do anything you want except identifying items by Cain and buying scrolls until you leave for the next town. Remember, if you use stash, you can't retrieve items from there till the accomplishment of the next act.

Going Back.
It is allowed to go back to any cleared location within current act within a current game session. E.g. - If you started a session from a "Black Marsh WP", you can go everywhere from that WP to the Andariel's lair. But you can't go to the previous WP's (like Black Wood or Stony Fields).

After you finished a current act you can also go back to complete quests and pick some items you've left (though remember, you won't be able to identify them by Cain). Since you are in town, you can use TP scrolls.

Quests.
All quests must be accomplished. That ones that require some visits to the town must be accomplished after the end of act.. You can immidiately use the rewards given in a process (e.g. - Book dropped by Radament in act 2). You can take all rewards that require going back to town only after the end of act.

You must complete all quests in a current act to move further. That means, yes, you have to use Charsie's reward in act 1, break the soulstone in act 4 and use a "socket" in act 5 - that because of you can't go back to previous locations at all costs.

You must kill all cows. No "save & exit" or running away from by TP or red entrance TP level is allowed until every cow is dead.

Monsters.
You don't have to kill every monster in a game. It's up to you how to clean up a level. Remember, if you just "go straight ahead" and don't run into every dangeon, you still get enough experience and levels even for the Hell Difficulty. E.g. - moving at a "normal" speed (not too slow and not too fast) you get level 73-74 on the beginning of Act One Hell Difficulty.

Items.
You can use any items, runes, stones you find and make in your MC game.

Mercs.
