Tactical Acumen

Even if you don't know much about its constituent creatures, you can always recognize a troop's capabilities through features like the formation they move in or even more subtle hints others might miss. You can always use Warfare Lore when you Recall Knowledge to identify a troop. This works like using an applicable Lore to identify a creature. If you're legendary in Warfare Lore, reduce any adjustment to the Recall Knowledge check's DC caused by the troop's rarity by 5.

If you lead a troop, when you successfully use Warfare Lore to identify a troop, that troop takes a –1 circumstance penalty to saves against your troop's offensive abilities until the end of your next turn.
