Add a hotkey that performs an action similar to placing a trinket ward. It places a circle roughly 1500 units in size. It cannot be placed within 1000 units of a structure. Hold tab and click on any champion to invite them into the circle. If that player accepts the challenge, only you and your opponent are allowed to enter the circle. You are untargetable to those outside the circle. Once you both enter the circle, neither of you can leave until one is dead.
