Question 1: Would FFG consider errata to Cheap Shot that allows one to commit skill cards with agility icons to the combat skill test that arises from this event?
Question 2: If you use this against an enemy engaged to another investigator, does it break the engagement?
I used the website form to submit a version of question 1, but never got a response.
I think the Rules Reference is clear on Question 1, the fight action is a skill test against combat, so you can only commit cards with combat icons. (You can still use Streetwise to pump up, though). However, I'm wondering if a slight errata would make sense in this case.
For Question 2, the Rules Reference is mostly clear, but there is still some doubt because it is not clear that the text has in mind a case where an enemy is evaded by one investigator while being engaged to another. In particular, the reference's text presupposes that an evaded enemy is engaged to someone: "Any time an enemy is evaded ... the enemy is exhausted (if it were ready) and the engagement is broken." Since the text presupposes that evaded enemies are engaged, it makes me think the text assumes that the evasion is being done by the engaged investigator. The rest of the text repeatedly refers to a particular investigator ("the investigator... that investigator...")
Still, I think the intention is for the engagement to be broken regardless of whom the enemy is engaged with. This matches the spirit of the wording for the massive keyword. Only ready massive enemies are considered engaged to all investigators in a room, so if one investigator evades the enemy, it will have mass disengagement as a consequence.
