The Lucky Bandos godsword (passive) is created by using a Lucky Bandos godsword on the altar in General Graardor's room. This process can be repeated to turn the sword back to normal. If this sword is destroyed, it can be reclaimed from Diango or Ianto, albeit in its non-passive version. The passive effect replaces the special attack.
It has a passive effect that can be toggled on by using it on the altar within the boss room of Bandos' Stronghold (the room in which General Graardor is located); however, entering Bandos' Stronghold requires level 70 Strength. It decreases the target's level in Defence by 1 if they are above 90% of their Defence level. This passive effect has a 25% chance of occurring with a successful hit. However, like most Godswords, the passive effect is noticeably less impressive compared to its special attack, in this case due to its slow nature and drain cap.
