While the Scarab Ring has long been the bargain benchmark for dual-duty weapons, another weapon, the Oversized Maractite Rune Sword, now challenges the ring for the title the best dual duty in the price class.
With twelve total icons, the ring still provides the best raw power-to-price ratio; however, the icons types are are weaker than those of the Oversized Maractite Rune Sword. Five icons from the sword slice through the ring while cutting the ring down to four icons. Likewise, the oversized sword splits the common Tooth of Terask in half while being untouched itself. In contrast, the tooth is untouched by the Scarab Ring while blocking two dark icons from the ring.
Nonetheless, there is no rule against using more than one dual-duty in a the same set. In fact, using both the sword and the ring together is usually a stronger strategy than pairing a pure attacker with a pure shield for the same amount of NP, though their overlap in physical and water attack make them quite vulnerable to many common shields.
