SC2Mapster

This is the associated mod file. Make your map with it and set it first on the dependency list. Now, when you import the library, the damage effects called by the triggers will be in your map already, saving you from having to wrangle shit in the data editor to make them do damage. Furthermore, the data mod contains the item-type units that add ammunition for the weapons, as well as the invisible dummy unit that enables enemy units to fight back.
