Guard

Help an exposed tower endure matching attacks.

Reduces damage taken by the named tower tier from the matching infected attacker.

When to choose it

Choose it when keeping an exposed tower alive matters more than increasing its firepower.

Limits to remember

It does not repair missing health, revive a destroyed tower, or make the defense invulnerable.

Read the tower portrait and any pictured infected role on your selected card. The ability applies to eligible towers of that tier for its designated wave. A new card replaces the previous choice; these are temporary abilities.

Merging into a different tier changes which cards apply. Check the tower you have after the merge.

Try this in your fortress

Watch the affected tower’s health and the GUARD feedback when the matching infected attacks.
