Kuban Energy is essential for leveling up your character and unlocking new skills. While you gain Kuban from defeating enemies and completing missions, there are more efficient farming methods. Repeatedly completing high-difficulty Base Defense Missions, especially with a coordinated team, yields significant amounts of Kuban. Focus on missions with bonus objectives for even greater rewards.
Another method is to target specific enemy types that drop more Kuban, such as the larger, more mutated Wanderers found in deeper dust zones. Equipping gear that boosts Kuban acquisition can also help. Consider crafting and using Kuban Extractors in the field, which passively gather Kuban over time. Prioritize upgrading your Kuban Converter at the base to increase its efficiency. Consistent farming will allow you to quickly level up and unlock powerful skills.
