During the mission in , you'll encounter a powerful boss called the Juggernaut, whose giant hammer makes them a difficult opponent to beat.
This Elite Naytiba enemy is the seventh major boss you face in the game as you explore the Matrix 11 area. You'll have to overcome the physical might of the Juggernaut over two intense phases to earn some rewards and progress through the quest. Exploring open areas and farming SP in may be a good idea before starting the mission to prepare yourself for the eventual battle.
With enough resources, you can upgrade EVE to gain new skills or abilities that could be incredibly useful against the Juggernaut.
Taking time between quests to grow stronger will ensure you don't always struggle against the next boss you face. One of the first strategies you should use against the Juggernaut is to stay at mid-range while fighting the boss in.
This keeps you just out of reach of the boss' massive hammer, a weapon that can easily damage EVE if you remain too close. As you can see in the above video by YouTube creator Elbethium, staying mobile at this range will always give you enough room to strike whenever you get the chance. Shock grenades are great for staggering the Juggernaut, sometimes knocking the boss down for a good amount of time when used to interrupt their attacks.
