I'd like a little clarification on what the adversary talent actually does. It says,
"upgrade the difficulty of any combat check targeting this character once per rank of adversary".
One of my players got into an argument with me because he thinks it means that if a NPC has rank 3 in adversary then that NPC can only upgrade the difficulty of combat checks made against him 3 times over the entire encounter, that is, if the NPC gets attacked once and uses its 3 upgrades it no longer has them for subsequent attacks. His argument was that the book said 'any' and not 'all'. He wouldn't listen to any of what I had to say. From what I understand it should be that the NPC gets to upgrade the difficulty 3 times on each attack made against him. A little clarification would be much appreciated. Thank you.
