Official Riftbound ruling

What happens when I play Moonfall choosing an enemy unit while I control an empowered Mel, Newly Awakened?

The chosen unit will be given -3 MightMight. All other enemy units at the chosen battlefield will be given -2 MightMight.

Mel, Newly Awakened’s empowered ability is a replacement effect. It replaces the event of a spell or ability you control giving a unit it chooses -MightMight. The event it replaces that with is the spell or ability giving an additional -1 MightMight.

Although Moonfall gives -MightMight to multiple units, only one of them is chosen, and thus the only event that is eligible to be replaced is the chosen unit being given -2 MightMight. It will be replaced with that unit being given -3 MightMight. The events of the other units being given -MightMight will not be affected by this replacement effect.
