Energy Shield Card

Fully Upgraded Energy Shield Card

Energy Shield Card provides a rechargeable shield that blocks the tower from taking damage from a single attack.

Use

Energy shield will activate at any damage that Tower takes, preventing it and going on the cooldown afterwards. That means that even small attacks from leaked enemies or shot from ranged enemy will trigger the Energy Shield. It becomes more useful later for glass cannon builds, where all enemies oneshot you.

It can also be used in conjuction with other revive skills to grind Death Defy Event mission on highest difficulty tiers.

The Energy Shield Card recharges over a period of time so wave skip and wave accelerator do not speed up the recharge rate. Game Speed will increase the rate the shield recharges. At max the shield will take more than 10 waves to recharge a charge.

The Energy Shield 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.
