General Strategy

Place Direct Counters

For this level, there is a surprising amount of variety with the enemy units, encouraging the player to set them up in a way that their units counter the opponents.

This speeds up wave progress as the enemies will be no match for the player's superior units in their respective combat scenarios.

Play Reactively

If the enemy breaches through your defenses regardless of the setup, react to it by placing down extra units where needed.

As much as possible, try placing them in a space where they can potentially cover 2 pathways, as they can support whichever side needs their help. The same applies for Stronghold Mechanisms.

Use Your Leadership Skill on Large Groups

For this level, the enemies can and will converge on your units, allowing you to get extra damage in by using your Leadership Skill while they are occupied with your lineup.

Doing this also has the added benefit of triggering Elemental Reactions, which significantly boosts the damage of your units during the fight.

Event Information

Stage Information
