===[ New Area #1, Graveyard ]===

How to Enter:
To enter the Graveyard, reach NG+1, then clear the forest and try to find a room with 3 red spikes in it (the music changes when you enter it). It may take clearing several forests to find it, so be prepared for that. When you find the room, suicide on the red spikes. The screen will slowly fade out and you will enter the Graveyard.

How to open the Boss Door + General Tips for traversal:
Just explore around randomly, when you've uncovered enough rooms an animation will play that shows the boss door opening. From that moment onwards, the boss of the area will chase you. You have to make your way back to the boss door without dying to fight him.
Sometimes rooms of this area will change to different rooms with new enemies in them after you leave. Keep an eye on your minimap to notice when it happens, and when it does, make sure you peak in the new room for a split-second, just to keep the map uncovered (very useful for orientation).

Tips for beating the boss:
Nah, you gotta figure that out on your own, I'm not gonna spoil EVERYTHING for you ;)

===[ New Area #2, The Ascent ]===

How to Enter:
To enter the Ascent, reach NG+2, then clear the tower and try to find a blue teleporter. When you find it, hop on, it will take you to the ascent. Keep in mind that you might need to clear multiple towers to find the teleporter.

How to find the Boss + General Tips for traversal:
Just climb up continually. The boss is on floor 200. Hope you can read roman numerals, otherwise just look out for the boss door. Enemies will get stronger gradually as you climb. You _can_ go past floor 200 if you really want to, but you don't want to.

Tips for beating the boss:
Nope. Figure it out on your own.

===[ New Area #3, Well of Sin ]===

How to Enter:
To enter the Well of Sin, reach NG+3, then find statues of christ in the darkness and renounce all your 7 sins at them. After that, you can use the christ statues to enter the Well of Sin. Since you need 8 statues you will have to do this across multiple characters.

How to find the Boss + General Tips for traversal:
Explore downwards. Not like you could go anywhere else. This area is very very deadly, so you should make sure you come prepared.

Tips for beating the boss:
Good luck. You're gonna need it.
