Jayce’s Mercury Hammer
A creation of Jayce back in his youthful days is the Mercury Hammer. With the help of the Hextech crystal, Jayce was able to use the Mercury Hammer while hunting down Viktor. Jayce’s Mercury Hammer can also transform into a cannon that can shoot an enormous amount of power.
Hextech Gauntlets
It’s not the gauntlet you see Thanos holding; it’s Vi’s Hextech Gauntlets! Using a pair of gauntlets and powered by Hextech, Vi can crush any obstacles in her way. The Hextech Gauntlet is also known as Atlas Gauntlets that gives the user an upgrade when it comes to their physical strength. Vi uses it also as a Blast Shield, Vault Breaker, and of course, heavy and damaging punches.
Switcheroo
Jinx is a fan of cannon, shooting, and explosions. She is also a creator in her way, and one of her inventions is the minigun, Pow-Pow. It allows Jinx to perform basic attacks and switch into another one of her inventions, her rocket launcher called Fishbones. Her switch from Pow-Pow to Fishbones explains why this is called Switcheroo.
Caitlyn’s Hextech Riffle
Working as Piltover’s Sheriff, Caitlyn specializes in guns and long-range shots. Hextech also powers the riffle that she uses, allowing her to perform heavy damages and capture criminals on the loose.
Viktor’s Hex Core
Viktor is someone Jayce knows because the two are the perfectors of Hextech. Like Jayce, Viktor created a weapon called the Perfect Hex Core. It is like a human brain that can learn, evolve and adapt to any situation. The Perfect Hex Core helps Viktor lessen his mistakes while building numerous machines. When used as a weapon, it can produce energy streams that are deadly enough to burn anything in their way.
