This most commonly comes up against the Habsburg Monarchy (Livestock Colony) Level 6, which can grant +2 Ravage Damage per land. If only Explorers are Ravaging, "Xenophobia" makes each of those Explorers deal 0 Damage to the land. Since none of the Ravaging Invaders can harm the land, there is no Damage to the land for the Adversary to increase. On the other hand, since the Explorers are still dealing Damage to the Dahan, the Adversary
can increase that Damage total by 2. (This can also arise with more complicated Invader configurations if Strife or the "Mesmerized Tranquility" Minor Power are involved.)
