How do you make a unit start with promotions/abilities? For example, making scouts start with the ranger/alpine promotions already? I want to change the recon tree so that they get access two promotions other than ranger/alpine. And how are unique unit's special abilities defined? I dont see them anywhere in units.xml. For example, hoplites get +10 combat strength when next to another hoplite. Where is that defined? Edit : I think I found the file, UnitAbilities.xml. So do I just put : <Row Type="ABILITY_IGNORE_TERRAIN_COST" Tag="CLASS_RECON"/> To make all recon units ignore terrain cost? And does anyone know how to make a unit get buffs per era, if that is even possible? Or do you have to make a seperate unit for it to upgrade to?
