If you're diving into Arknights Endfield, mastering battles against Origin Lodespring and Surge Towers can significantly boost your gameplay experience. From my personal experience, positioning your Operators strategically is crucial. Focus on deploying strong vanguard units early to build up deployment points quickly. This allows you to bring out your heavier damage dealers like snipers and casters at the right moment. During fights against Origin Lodespring, it's important to manage your crowd control effectively. The energy Alluvium Origin Lodespring often spawns continuous waves, and without careful area damage, they can overwhelm your defenses. Consider operators with skills that can hit multiple enemies or apply debuffs to slow their advance. For the Surge Towers, which tend to have higher defense, using Operators that can bypass or reduce defense will save you many headaches. Operators with piercing attacks or those who can reduce enemy armor stats are particularly helpful. Remember to always upgrade your Operators and their skills to match the enemy level — many players underestimate the impact of skill levels on survivability and damage output. Also, keep an eye on your deployment limits and prioritise resetting your Vanguard if needed, as their early deployment generates crucial resources. Finally, don’t be afraid to experiment with team compositions. Each player’s available Operators differ, so finding a balance between damage types, healing, and crowd control that suits your roster is key. Over time, I found mixing melee defenders with ranged healers and snipers provided a solid frontline and backed-up ranged suppression. By combining these tactics with awareness of enemy attack patterns seen in the "Alluvium Origin Lodespring" and "Surge Tower" stages, you can consistently overcome even the toughest levels in Arknights Endfield.
