Rune defender

The Rune Defender is the strongest defender. It is used for the attack bonus and is held in the off-hand in place of a shield. It requires 40 Attack and 40 Defence to wield. The Rune Defender is dropped by Cyclops on the top floor of the Warriors' Guild, but players have to show either their Adamant defender or Rune defender (player may obtain multiple Rune defenders if they want) to Kamfreena to obtain this as a drop. Ring of wealth does not affect the chances of getting it as a drop.

Their slash and crush defensive bonuses are the same as a black kiteshield, however their stab defence bonus is slightly less than an adamant square shield. It gives a similar bonus to strength as the obsidian shield, however, it is much more commonly used due to its Attack bonuses for melee. A Rune defender is commonly combined with a Dragon scimitar or Abyssal whip for its strength bonus.
