Level 1:
Prioritize upgrading area-of-effect (AOE) skills. Either Skill 2 (Stun) or Skill 3 (Knockback) works. Upon reaching Level 6, prioritize upgrading Skill 4 for significantly increased damage.
Destroy monster barriers to cluster enemies together, then unleash your skills to maximize damage output.
Continuously protect the blue crystal (its destruction results in game failure), as it also restores your character's HP and MP.
Aim to reach Level 18 if possible.
Level 2:
A bit of luck is involved, as there are 5 sub-commanders, one of whom will randomly defect.
Lure the sub-commanders away from the enemy barracks (which heals enemies).
Pay attention to skill timing; sub-commanders will flee back to the barracks when their HP drops below 40%. Use stun skills at this point to immobilize and eliminate them.
Manage your MP consumption; avoid spamming skills to prevent running out of MP.
Level 3:
At the start, prioritize eliminating the enemy sub-commanders, then focus on destroying their defensive towers.
Protect the defected sub-commander; when their HP is low, bring them back to your camp for healing.
After destroying a defensive tower, your faction gains 5 assault troops. Use them to quickly break through enemy defenses.
Level 4:
The enemy general has extremely high defense. Lure them near your camp, where your troops and towers can combine forces to defeat them.
Defeating the general spawns 10 enemy sub-commanders, requiring a defensive-offensive rhythm switch.
Attacking enemy defensive towers will cause the general to return, which can be used to relieve defensive pressure.
Use a whistle to command your troops to follow your character, enabling tactical maneuvers (e.g., ambush or defense).
