Wizkids Rules!

The text of the card says

When you perform a Target Lock action, you may disable this card to acquire a 2nd target lock on a different enemy ship within range 1-3 of your ship. While you have this upgrade on your ship, you may have up to 2 different enemy ships target locked at the same time.

Typically when a card is disabled, the card text has no effect. Does the wording of "While you have this upgrade on your ship...." mean that the Multi-Targeting Phaser Banks card works to maintain up to 2 target locks even while disabled?

Yes, as long as the Multi-Targeting Phaser Banks is present on your ship you may maintain 2 Target Locks.

Does this ruling also apply to Dispersion Field

"While this card is deployed to your ship, none of your other upgrades can be affected by your opponents...."

Errata:

"When you perform a Target Lock action, you may disable this card to acquire a 2nd target lock on a different enemy ship within range 1-3 of your ship. You may have up to 2 different enemy ships target locked at the same time even if this card is disabled.”

We will be issuing an errata for this card in the next posting of the FAQ.
