How to make it so that rom_building_unit_equipment_weapon gave a bonus to damage (armour piercing damage, swords/spears/bows/javelines), and not bonus to attack?
rom_building_unit_equipment_weapon is the effect of iron_weapon building chain.

Another link to the problem - unit_stat_bonus_weapon. It is bonus_value_id of rom_building_unit_equipment_weapon_[bronze/silver/gold] effect. Apparently it modidfies melee atack, but not weapon damage.

For example:
There is right effect bonus (damage bonus) from blacksmith building chain in Attila. But cant find where effect config in tables..

Does no one know how to do this? Comrades!
