Blight

Blight is a core keyword that denotes that a unit or item is infected with disease, illness, etc. If a unit takes any amount of damage from something with Blight, that unit loses 1 Loyalty per round until it dies or is given a vaccine. The distinction here is that if its loyalty reaches zero, it does not go to the Wasteland, but to the Beyond. Units that go to the Beyond are dead and cannot be brought back into play. Stricken units also cannot be augmented until they are cured. This means that an infected unit cannot be given +X effects (on anything), either through actions, items, hideouts, or other units.

Card Text
Stricken units lose 1 loyalty per round until DEAD or given a vaccine, and loyalty cannot be augmented unless they are first cured.

Usage in Decks
Cards with Blight can be found in any color of deck.

Examples
Glen's unit attacks Linda, whose unit has 4 Loyalty. Glen's unit has Blight and deals 1 damage. Linda's unit's Loyalty is now 3. Next round it reduces to 2, and the round after that it reduces to 1. Finally, when it reaches zero, it goes to the Beyond. If Glen tries to offset the recurring damage by using a Holdover Bar, for example, it will not work unless the unit is first cured with a vaccine.
