Furious
From Guild Wars Wiki
Furious is a weapon upgrade that grants a 2-10% chance that a successful completion of an attack, attack skill, or skill that grants adrenaline will yield twice as much adrenaline than it would otherwise give. For example, with 14 Swordsmanship, a successful hit with Dragon Slash that triggers the double adrenaline gain from Furious will give 12 strikes of adrenaline instead of 6.
