Is there any way to make a weapon do effective or extra damage against a unit with a certain type of weapon equipped? My idea was to make an “Anti-siege bow” that does extra damage to ballisticians and bolting/purge/eclipse users, in the hack I’m developing ballisticians are their own class (which is enemy/npc only, if that’s relevant), but I want to know if there is a way to make a bow do effective damage against a sage that has bolting equipped but not if it has any other tome.
