If you have an unpatched version of the game, this glitch still works. The engraved gauntlets give a chance for a normal hit to do the damage of a critical hit, like a backstab or riposte. Keep attacking until you trigger a critical hit from the gauntlets, then take off the gauntlets. Every hit will now become a critical, for a lot of damage. Will only work on PvE because you cannot play online without patching your game.
Gender Change Coffin
There's a coffin in Things Betwix in the sand circle where the fat big guy stand. If you enter in that coffin your character will swap its gender with the major facial details.
Secret Darklurker Boss fight
The optional Darklurker secret Boss is found in the Dark Chasm Of Old, past a series of extremely challenging enemies. To enter the Dark Chasm Of Old and fight the Darklurker, you must join the "Pilgrims Of Dark" covenant and reach Rank 2. Complete the listed requirements under the "Joining covenants and rewards" information below. Once you have opened the gate to the Dark Chasm Of Old, you need to reach and defeat a series of enemies in three sections in the area. Defeat the enemies in each section, and light the sconce at the end with your torch. Light all three braziers and speak with Grandahl to activate the elevator leading to the Darklurker. Note: If you die in the Abyss, you must offer a Human Effigy to Grandahl to re-open the portal. When you are Rank 2 in the covenant, the elevator inside the Dark Chasm Of Old will activate. Travel through the Drangleic Castle portal to reach it.
Secret Dragon Memory
Towards the end of the game, you will have to travel to the Dragon Shrine to obtain the Ashen Mist Heart from the Ancient Dragon. The Ashen Mist Heart allows you to travel into the dark memories of the past. You can use the key on hollowed giants in the Forest Of Fallen Giants. You must fight the Giant Lord by entering one of these memories to proceed. However, there is also a secret place to use the Ashen Mist Heart. After obtaining the Ashen Mist Heart, travel to the Duke's Dear Freja arena, and a new crystal will appear under the hollowed dragon. Interact with it to enter the Dragon Memory. You will be taken to an arid wasteland resembling the dragon battleground described in the original Dark Souls. Interact with the ancient dragon's corpse to acquire an Ancient Dragon Soul.
