This sounded like tricky challenge, so I tried it out. wesnoth.get_units{formula="abilities"} worked to find units with abilities, so in filter you can use formula=abilities.

I'm not sure I understand the question correctly, but weapons don't have abilities. If you mean "weapon special," this code shows how I would do it. This "ability" currently blocks all magical attacks. You can modify it to block the weapon special you want. The weapon special could filter the attacker based on that unit's ability instead if that is what you want. You could #define it and add it to all of a unit's attacks as well.

Code: Select all

# This ability does nothing except allow the user to see it. The affect is
# really acheived by the weapon special. (You don't need to use "dummy". You
# can use any tag that doesn't already exist.)
