Low Rarity Squad Composition
Best Low Rarity OperatorsPlace Operators From Left, Right, Center
Enemies in this mission have 2 spawn points with the following paths:
- Left enemies go to the left base
- Right enemies go to the right base
- Right enemies go to the left base
Have 2 Operators on each side first to deal with the preliminary threats. Afterwards, back them up with a Medic placed at the center.
Hit Enemies At The Center With AoE Casters
Plop down some AoE Casters at the center to rain down damage to those transiting the bridge. Most of those passing through this path are weak against Arts. Take advantage of this and add an AoE Caster to your team.
Use A High DPS Guard
Place a Guard with high ATK to defend the center path. Use AoE Guard operators like SilverAsh to easily dispatch the waves.
Use Special Medics
Placing 2 Operators and 1 Medic on each lane will exceed the 8 Operator placement limit. To counteract this, use Medics like Silence for her healing drones, or one's that ignore the placement limit like Lancet-2
