Unlimited Souls (Exploit)
Find a corpse with an item or souls, and grab the loot. Now make a fatal leap off the nearest ledge. As soon as you die, quickly press the appropriate button to bring up the option to quit your game. When you restart, you will be at the last bonfire with whatever you picked up from the body now located within your inventory. If you go find the body, the item should also be waiting on the body, allowing you to pick it up again and repeat the process as often as desired.
Easy Trick to Defeat the Executioner's Chariot Boss
In the Arena, kill the first Necromancer enemy, along with any nearby skeletons. Stay in the door area and cast Affinity. As the chariot drives past, the spell will hit it. In this manner, you can kill Executioner's Chariot boss without moving further into the area or lowering the gate.
Change Character Gender
Right after Things Betwixt, in the game's first area, you should notice a small beach with two ogres. Behind those ogres, you'll see a partially opened coffin. If you hop into the coffin, you can switch your character's gender. The coffin apparently does not serve any other purpose.
Secret Use for the Petrified Something
The Petrified Something is an optional starting item Gift in Dark Souls 2. Available during Character Creation, the item has no apparent purpose.
However, when placed in the bird's nest in the game's very first area, Things Betwixt, the Petrified Something may be exchanged a random item, from a near-useless Old Whip to the extremely precious Twinkling Titanite, an item which allows players to upgrade equipment otherwise resistant to improvement.
False Wall in No-Man's Wharf
Near the far edge of No-Man's Wharf is a small room full of jars containing poison. Two guards sleep at the table.
The wall behind them is false and can be blown out with a spell. Hidden behind are a number of Souls and the useful Royal Soldiers Ring.
More Difficult Gameplay with the Company of Champions
Just behind the village in Majula is the Victors Stone, a shrine to the Company of Champions. Joining this Covenant significantly increases the difficulty of Dark Souls 2, a fact not made crystal clear in the process of joining the cult. If you want to increase the challenge, (and potential rewards) of Dark Souls 2, join this company.
Easy Trick to Defeat The Pursuer
The Pursuer can be weakened 99% by a single shot from one of the Ballista set-pieces in his boss arena. Lining him up requires some pretty precise timing, but a clean hit all but destroys him.
