Wizkids Rules!

Does the damage taken from a critical come into play automatically, or only once you flip the card over to show the damage symbol on the other side of it?

IE
Take one damage and flip this card over

= 2 damage

vs

Warp Core Breach

Hasn't been flipped, so no actual damage to hull, but the effect of the card is in play.

Both damage (face down) and critical damage (face up) count as points of damage against your hull. A Warp Core Breach (face up with the text showing) counts as one damage as well as having the text shown.
