Jett had died very quickly, perhaps because he was terrified that Zane had slipped past his defenses without making a single hint that he had done so. But Zane shocked himself with his speed. He had moved so swiftly in the attack; he felt it was basically impossible for anything to stop him from launching an attack.
He knew, of course, this was nonsense. A Tier II Horde King could easily match his speed, or would even prove superior in such regard. And because of this, Zane calmed his racing thoughts while looking at the blood crystal, which appeared in his inventory.
The system had auto looted Jett's corpse, and like usual, the rewards of his efforts were found in the inventory page which clearly displayed the large and golden Horde Crystal which belonged to a Horde King.
