Greatsword

Obtaining

 * Found in the back of a Great Coffin northwest of Caelem Ruins (Caelid).

Trivia

 * The Greatsword is a reference to the Dragon Slayer, one of the signature weapons of Guts, the protagonist of the manga series Berserk by Kentaro Miura. The weapon's description reinforces this, with "coarse iron lump" referencing the description of the Dragon Slayer as a "far too rough [...] heap of raw iron". Additionally, the mention that the Greatsword is used to slaughter inhuman foes references Guts' battles against demonkind throughout the series.
 * It is sometimes called the "Guts Greatsword" in the community, both to reference Berserk and to distinguish it from the weapon type.
 * The Greatsword is a recurring weapon in the Dark Souls series, having appeared in all three games with the same name and a very similar design.
