Obsidian Greatsword is a Weapon in Dark Souls and Dark Souls Remastered.

 

 

This greataxe, one of the rare dragon weapons, is formed by the tail of the one-eyed black dragon Kalameet, the last of the ancient dragons. The mystical power of its obsidian blade will be released when held with both hands."


 

How to Get / Where to Find the Obsidian Greatsword

  • Obtained by cutting off the tail of Black Dragon Kalameet. This is difficult to do, as the opportunities to do this without ranged weapons are short and infrequent without the help of phantoms.

 

Notes:

 

  • Give to Frampt to receive 100 souls.
  • The Two-handed R2 creates black flames over a 360-degree Area of Effect around the user. Note that the flames deal physical damage and not fire damage. These flames cause significant poise damage and almost always stagger targets, including bosses.  For this reason, the sword can be used very effectively against Artorias, among others, notably during the long windup to his charge attack. 
  • When the strong Two-handed attack is used 50 durability is consumed.
  • Only 14 Strength is required to use it if held in both hands.
  • Despite being referred to as a Greataxe, it is classified as Greatsword. It is a simple typo, and this weapon is actually a Greatsword.
  • This weapon can also be buffed. Buffing this weapon also increases the damage dealt by the special R2 attack, dealing an appropriate amount of damage of the type determined by the buff. For example casting Sunlight Blade and then using the Two-Handed R2 not only causes it to deal more damage, but to deal that extra damage as Lightning elemental damage.

      Hitting the tail after the tail attack is the most long way... You can just hit it when he uses the red energy grab or the flame spit in the same position of the grab. They are not rare attacks, you can gust stand in front of him and wait for him to stand up on the posterior legs and rush to the tail.

        Thank god the demons greataxe cut off his tail in one hit I don’t find kalameet to really be that hard personally but I died so many times sprinting around his backside to get to his tail before losing track of him as the camera got stuck in his gut

            After dying countless times trying to even get a shot at this bastards tail, I finally realized that it was futile and decided just to kill him so It would stop me from the madness! NO MORE DOGS!!! I attuned power within, put on my sorcery ring and that sorcery wing head dress thingy and went to town, he did his flyover and one of my crystal soul masses mysteriously hit his tail in flight and I got it! Now after 1500 hours of game play over 2 years on 2 platforms I *think* their is nothing else I to discover or accomplish in this game, but who knows. Goodluck!

                Testing taking a hit from the same attack while stationary with and without the weapon equipped. It seems like I take more damage with it equipped.

                  How good is this thing in endgame? I’m reading a lot of good things about it, and I’m very curious indeed.

                      High damage when fully upgraded (unlike the dragon great sword that even at max lvl does only 200-300 damage) but still not a good weapon for bosses such as 4 kings and death

                        If you are going for minimum requirements you have the stats to two-hand the gravelord sword. It’s a good choice for cutting the tail at a low level. The running attack is fast and powerful. Easiest way to cut the tail solo is to stay at a medium-far distance away from him to bait the diving attack. When he flies at you roll to the left, get behind him and position yourself directly beneath the tail. This will bait his tail slam attack allowing you to get 1-2 free hits. Remember you MUST position yourself DIRECTLY beneath the tail otherwise he will not follow up.
