Warsoul sword

The Warsoul sword is a large two-handed sword and one of the four weapons of the Deraill and it is dropped by Deraill Generals after the quest Grain Of Lost Time has been completed. Similar to the Godswords, it requires 75 Attack to wield. Its special attack, "Brandish", inflicts 30% damage over 8 times on the target and reduces the targets attack speed by 50% for 20 seconds. The special attack drains 100% of the special attack bar (or 90% while equipping a Ring of Vigour, obtained with Dungeoneering Tokens).

This special attack is very similar to the Dragon claw's special attack which inflicts four times the regular damage. It is also comparable to the Dragon claws' special as it only drains 50% of the special attack bar, meaning it can be used twice back-to-back inflicting a total of eight times regular damage, increasing the ultimate total damage output to 800% in comparison to the Warsoul sword's 240%. But a far superior strength bonus along with a devastating side effect pits the Warsoul sword ahead of the Dragon Claws in terms of usage and damage capabilities. It has been recorded the highest hit for the Warsoul sword's special attack to be 856 (8*107) although the highest possible hit with the special attack is said to be 920 (8*115).

Uses
The Warsoul sword can be obtained by buying it from the Grand Exchange or by trading it with other players prior to the completion of Grain Of Lost Time but the quest is required to wield it. It is mostly used as an alternative to a Godsword and the Dragon claws, aside from its +2 Prayer bonus in comparison to the Godsword's +4, it boasts slightly higher stats to the Godsword along with the devastating special attack similar to that of the Dragon claws.

The sword is used in many cases from regular Player vs Monster combat to PvP combat. Due to its extremely high price and slow attack speed, it is seldom used for PvP in the Wilderness. Though some players find it as an ideal weapon of choice to takedown selected opponents, but most others would rather go for the cheaper alternatives like stated.

It is, however, a good weapon of choice when going for boss hunting. Especially effective against General Graardor and Tormented Demons. The special attack's ability to slow down the opponents attack speed by half is extremely useful against a handful of bosses, namely bosses like the Dagannoth Kings. However, this does not affect the Corporeal Beast, TzTok-Jad or the Queen Black Dragon, unfortunately.
