Problem with Suit of Armor curio

[kamanin_igor]

I went through the Ruins and have found Suit of Armor in the room. According the wiki, it can give a buf or Quirks Ruins Adventurer or Ruins Tactician. My Reynauld already had Ruins Adventurer quirk, and Suit of Armor HAS LOCKED IT! I trained him for achievement "On the old road, we found redemption" so this quirk is absolutely useless for him, and I can't unlock it.That's a pity...

This is not a problem. One useless quirk will not affect final encounter significantly. Besides, you need only start final quest with 2 heroes, winning is not required.
