Koga can be so confusing. But in reality is not. Place your teleport first and Aslong you watch koga movement you can win the duel. Have max shield would give you time to read the situation first between fight koga or enter teleport
Max your shield. Place teleport first and try to track evie when she about to engage you. If she about to landing, then spam the landing place. And in duel 1v1 you need to jump or moving right left or both because she might miss her shot.
