The rune 2h sword is a two-handed sword that is made of rune. It is stronger than the Adamant 2h sword, while being weaker than the Dragon 2h sword. It can be made using the Smithing skill at level 99 using 3 runite bars and a hammer on an anvil granting 225 Smithing experience. It requires 40 Attack to wield.
The rune 2h sword is often used on free worlds as a player-killing weapon, due to the fact that it has the highest strength (equal to the Hill Giant Club) and the highest slash bonuses of any free to play equipment.
The rune 2h sword can also be dropped by any monster who has access to the rare drop table.
