Cards/Second Wind Card

File:Cards/Second Wind Card.png

Fully Upgraded Cards/Second Wind Card

Cards/Second Wind Card Revives the tower after taking lethal damage and giving invincibility for a period of time.

Use

Upon taking fatal damage card will revive the tower with half health and will add an invincible shield for up to 40 seconds depending on the level of the card.

With Lab research it can also clear up to 100% of enemies on the screen after triggering and with the recharge research can be used more per once during the round (with maximum research 400 waves cooldown).

The Second Wind Card is one of 3 abilities that automatically prevent death. Each work together by activating in a specific order. In case of the fatal damage game will go through them in the following order:

1. Death Defy: Triggers first. If activated none of the next abilities will activate since the tower does not take damage.
2. Energy Shield: If Death Defy fails and an Energy Shield charge is available, Second Wind will not activate because no damage is taken.
3. Second Wind: If Death Defy fails and Energy Shield does not have a charge, Second wind will activate.
