To be able to warp between Bonfires in Dark Souls (and even then you can't just warp to any one you want), you need to acquire the Lordvessel. To get this, you first have to ring both Bells of Awakening, before finishing Sen's Fortress and reaching Anor Londo. Defeat the bosses there and the Princess will give you the Lordvessel.
This will then allow you to warp between the bonfires below, once you have discovered and activated them:
Altar of the Gravelord (at the Tomb of the Giants) Altar of Sunlight (in the Undead Parish) Anor Londo (the one by the Firekeeper in Brass armor) Chamber of the Princess (Gwynevere, Anor Londo) Darkmoon Tomb (at Anor Londo) Daughter of Chaos (between Queelag's Lair and the Demon Ruins) Firelink Shrine Stone Dragon (at the end of Ash Lake) The Abyss (beneath New Londo)
Below is a list of the rare weapons in Dark Souls, as well as how to come across them in game:
Gargoyle Axe: Cut off the gargoyle's tail to get the Gargoyle Axe.
Dragonking Great Axe: For this axe, cut off the Gaping Dragon's tail.
Moonlight Greatsword: The Moonlight Greatsword requires you to remove Seathe the Scaleless' middle tail.
Dragon Greatsword: Cut off the tail of the Covenant Leader for Path of the Dragon, the Everlasting Dragon. This won't make him hostile, but you should ensure you actually attack his tail rather than his body.
Drake Sword: Remove Drake's tail for this sword.
Priscilla's Dagger: To get Priscilla's Dagger, you have to cut off Priscilla the Crossbreed's tail.
In Dark Souls you are able to see messages from other players scrawled on the floor of the game world. You can also write these yourself. They appear with a different image next to them depending on how other players have rated them.
To rate a message or write one of your own, you need Orange Soapstone. You can buy this from the merchant in Undead Burg. You can use it whenever you like and it will not be consumed. Select 'Use Item' and you will be able to write a message. Select it while standing over another message, and you'll have the option to 'Rate Message'.
Beating the final boss in Dark Souls is actually easier than you might expect. In fact, it is possible to defeat it without taking a single hit. The first thing to consider when taking on the final boss is to parry as much as possible.
You can parry and riposte the boss until he has zero health and without taking any damage. If you are struggling with this, remember that the boss specializes in Fire attacks, so use Flash Sweat to absorb some of this damage and use a Black Knight Shield for additional Fire resistance. Try to attack after every four-hit combo that the boss sends your way.
You can use the arena's pillars to lure the boss to, then run around them to stay out of his reach. This can buy you the time you need to drink an Estus Flask, and just generally helps if you need a breather.
For cutting off boss's tails, you can employ a variety of tactics. For example, using a Claymore gives you the ability to reach the boss with relative ease, while you can also use magic spells, such as Lightning Spear and Fireball.
How to easily defeat the gaping dragon in the depths

You will need a overhead slash weapon (like a halberd or axe or great axe and whatever armour you want. A shield that blocks 100% phy damage and lots of stamina When you enter the arena don't charge it let it come to you but try to keep it away from the walls and wait for it to charge then when it's recovering hit it's tail with the overhead slash (running one-handed light attack for halberd heavy one-handed standing attack for axe and great axe) attack around a faint ring at the base of it's tail for a quick sever after tail is severed wait for it to charge then attack it. Then repeat to kill but always be cautious. NEVER stand in front of it if you are close to it. Try to keep it away from the walls but you don't have too and don't get boxed in as almost all it's attacks are one hit kills. Don't risk an extra attack only hit when you know you wont be hit.
