Fortnite's Infinity Blade is a mythical sword that kills in one blow

Update:  The sword Epic teased last night is the Infinity Blade, the titular weapon from the developer's mobile game, and you'll be able to get your hands on it today. It's a mythic sword only found on Polar Peak and only one will appear per match. 

The Infinity Blade can destroy buildings and kill enemies with one hit, doing 75 damage to humans, and there's an alternate fire that lets players leap great distances and cause plenty of destruction. 

Wielders of the sword get supercharged—thanks, magic!—with increased health that also regenerates at 1 HP per second, a burst of health with every slain enemy and increased movement speed. 

You can only carry the sword, however, and nothing else, aside from building materials. If you pick up another item, the sword gets dropped and someone can pinch it right from under your nose.
