The ASN-30 is correct. There's no requirement for 1 damage, minimal damage applies to all damage.
Thanks. I think the FLK special is the only one that doesn't specifically reference minimal damage or minimum damage. The other specials which do not have a minimum specifically call it out in their descriptions.
REAR states "...rounding normally, with pre-rounded damage values between 0 and 0.5 represented as a Minimal Damage (0*) value." (ASC, pg. 129)
IF states "(If the unit’s Indirect Fire attack value, after heat-modification and before final damage rounding, is greater than 0, but less than 0.5, the unit receives an IF0* special..." (ASC, pg. 125)
All other specials have a minimum damage requirement, but they also state it. So I think with FLK, the way it's written, you're left guessing. Can we add some errata so it is clearly defined, and keep it inline with the other specials?
