Chaotic longsword

The chaotic longsword is a melee weapon released with the Dungeoneering skill on 12 April 2010. The chaotic longsword requires an attack level of 80 and a Dungeoneering level of 80 to wield. At least two million Dungeoneering experience is required to attain the 200,000 tokens needed to purchase this item.

The chaotic longsword is one handed, meaning players can wield an item in the shield slot. When wielding a rune defender, the slash and strength bonus will increase to 143 and 125 respectively, making the weapon more accurate than godswords. It is ideal for a variety of combat situations, including boss fighting at the God Wars Dungeon, Player vs Player combat, and even general training and fighting if the player can afford the upkeep. Many players believe that this weapon is the best weapon with which to kill the Corporeal Beast because of its high stab and strength bonuses. Despite its high strength and stab bonuses, its damage seems to be halved against the corporeal beast.

After approximately 10 hours of combat, the chaotic longsword will degrade completely and must be recharged before it may be used again; it has a 20% charge on purchase. Once these charges have been used up, the weapon can be recharged for a fee by the rewards trader. There are two methods of recharging: cash, or a combination of cash and dungeoneering tokens. Repairs cost 20,000 coins or a combination of 2,000 coins and 200 tokens per 1% charge. A completely degraded longsword, for example, could be repaired with a choice of 2 million coins or 200,000 coins and 20,000 tokens. The chaotic longsword appears to be similar in shape to the promethium longsword.
