If Invaders Ravage twice in the same round and deal 1 damage to the land each time, do you add a Blight? How does Defense work?

• Defend Powers apply each time the Invaders do Damage in a land.
• Each time the land itself is Damaged is separate - it does not accumulate Damage during a turn the way Invaders and Dahan do. Only add a Blight when a single instance of Damage is enough to cause Blight.
• Similarly, Blight can be added to a land multiple times in a turn. Check each time it takes Damage.
