The Protectors of Etheria is a stand-alone mod of the game Warlords Battlecry 3 (i.e. it can be run without having the original game installed - 100% free full game). It is an improved RTS/RPG game with new campaigns, quests, terrain, units, items, heroes, modding features and more. Beta versions available for download!
0.9.2 is underway and it brings back the armour system but with a twist - it functions more like it did in WBC1 and WBC2 where there's no one armour stat that works for all damage types but instead one for each type. This allows units and buildings to have a broad range of varying armour values across all damage types that is also thematically. Skeletons, for example, can now be incredible resilient to piercing attacks with decent armour vs cold. But heavily weak to crashing and not so great against fire.
As such, the armour display will also change to be more like that from WBC1 and WBC2 - using coloured bars to help quickly indicate how good an armour value is without needing to look too much into it. The more blue the bar, the stronger it is. The more red, the weaker it is. The numerical values are still present for those who want to know the exact figures.
