Astora's Straight Sword

Astora's Straight Sword is a straight sword in Dark Souls.

Obtaining
Taking the tunnel under Darkroot Basin (there is a Black Knight guarding this tunnel); you will find a bonfire. Past the bonfire, you find a lift leading down to the Valley of Drakes. After defeating the first drake, you can either take the bridge, or the path to the left. If you elect you cross the bridge, you will be warmly greeted by another four drakes but you can also obtain the Red Tearstone Ring.

Ignore the bridge and take the left path, heading along a cliff side, where you will find much less resistance. After slaying another drake, continue along the path until you come across what appears to be a large moss-covered rock spanning the gap between the narrow path you are on, and the path on the alternate side of the valley. This is actually an Undead Dragon, one of the few remaining dragons in the world. Defeat it, using your preferred attack style. Among the treasure in the corpses the dragon guards, is Astora's Straight Sword.

Characteristics
Astora's Straight Sword can be obtained as soon as the player reaches Firelink Shrine if they have the Master Key, and should he/she have the strength, dexterity, and faith requirements to wield it, it can prove to be a very handy sword early on, being only slightly inferior to the Drake Sword in terms of damage when unupgraded.
