Chaotic longsword

The Chaotic longsword is a melee weapon released with the Dungeoneering update, on 12 April 2010. The Chaotic longsword requires an attack level of 80 and a Dungeoneering level of 80 to wield, however, the tokens needed to purchase the item require 2 million Dungeoneering exp to gain. Despite its stab accuracy being much higher than that of the Zamorakian Spear's, it is not possible to hit over approximately 290 with it (much like Vesta's Longsword). The Chaotic longsword is one handed meaning with rune defender wielded on the other hand, The slash bonus will increase to 143 and 125 strength bonus. This makes the weapon more accurate than godswords yet it hits faster. It is ideal for a variety of combat situations, including boss fighting at the God Wars Dungeon, Player vs Player combat, indeed even general training and fighting, if you can afford the upkeep. The Corporeal Beast does NOT have damage reduction against this weapon, or any of the other Chaotic weapons.

After approximately 10 hours of combat, the Chaotic longsword will degrade completely and must be recharged. Each chaotic weapon starts at 20% charge. A fully recharged weapon will last 10 hours in combat before it cannot be used. Once these charges have been used up, the weapon can be recharged, for a fee, by the rewards trader. To do so, right-click on him, and select 'Recharge' with the depleted weapon in your inventory.

There are two methods of recharging: cash, or a combination of cash and dungeoneering tokens. A cash repair will cost you up to 2 million gp (for a weapon with no charge at all). A combination of cash and tokens will cost you up to 200,000 gp and a number of dungeoneering tokens (for a weapon with no charge at all).
