Taurus Demon

The Taurus Demon is an enemy in Dark Souls first encountered as an optional boss in the Undead Burg. Smaller demons are later encountered as respawning enemies in the Demon Ruins.

The Taurus Demon is a large, bipedal minotaur-like monster, at least twice the player's height, covered in brown fur and large horns and wielding a Demon's Greataxe

Any Taurus Demon, including its boss form, has a chance to drop the Demon's Greataxe.

Giant Swing
At the start of this attack the Demon will draw back its weapon briefly, before initiating a huge swing across a horizontal arc in front of it. This attack does not have very much range, so it can easily be evaded by backstepping once you see it draw its weapon back. Alternatively, you can roll towards the Demon and go under the attack, which will allow you to get some quick hits in.

Jumping Pound
If there's too much distance between you and the Taurus Demon, it will use the Jumping Pound to close in rapidly. The demon will crouch down, and then it will jump towards you and deliver a long range vertical attack. As soon as you see the demon crouch, either run towards it and roll past the attack, or continue moving backwards to get out of range.

Quick Ground Stab
Another attack that the Demon will only use when you're close. Because it is one of the quickest attacks, it's the primary one you need to be wary of. The start of the attack is quite similar to the Standing Pound, but the follow up is much quicker. You can still move around to the back of the Demon during the start of the attack, but be ready to roll to the side in case you do not get around in time.

Standing Pound
This close range version of the Pound is only used if you're very close to the Demon, and is also much easier to avoid. Wait until you see the Demon raise its hammer into the air slowly, and as he commences the attack. walk around to his back. From this position you will be safe to attack before it recovers.

Trivia
Even tough it's possible to skip this boss, for new players it's not worth it, as it requires passing through high level areas and it's a much longer path than going the Taurus boss fight path, for experienced players tough, it allows the acquiring of better loot and souls at early game.
