"$0" refers to the first entry in the repeating list, so for the second weapon you use "$1"...
If I only had known that earlier.
I got rid of the repeating list element in my TOR character sheet (German version only) because it didn't work with the macros as it should. The workaround I proposed in the wiki:
Note: I experienced issues with weapon attributes not being created when I entered the weapons in the Adversary section of the character sheet. However, when I entered the weapons (and only the weapons) in the Player Character section of the same sheet it worked perfectly.
Would you like to update the wiki or should I? https://wiki.roll20.net/The_One_Ring#Macros
