Figures treated as heroes may use one of their available actions to perform an action on a Condition card (e.g. to remove Stunned, Bleeding, and Burning) or to climb out of a pit space. Removal of conditions from the figure itself has been clarified by an FFG answer e.g. in this post.

Question: Can a figure treated as a hero also remove Burning from an adjacent hero?

It does say "you or a figure adjacent to you" so I would think... yes? This has someehow never come up.

Yeah, the question here is if a figure treated as a hero might be able to use these special actions printed on a Condition card only when it is affected by the condition itself. The FFG answer is not clear in this respect: " If Friedrich or a Reanimate becomes Stunned, Burned, or Bleeding, they gain the ability to spend one of their actions on the action granted by the card."

I guess, that this wording is not intentional and a figure treated as a hero would be able to discard burning from an adjacent figure. Just wanted to know if you guys agree with this interpretation.

I can't claim to know the "official" answer, but this is how we always played it since the ruling ... that is to say, we do allow figures treated as heroes to use an action to get rid of a condition for themselves or someone adjacent (when appropriate based on card text).

I really think FFG should be asked for intention on this matter, though the way the card is written seems to imply they can do this. I'm just wondering if the general "figure" is used to avoid the wordy "hero if you are a hero and monster if you are a monster".
