Before this patch added crush armor as forge techs. I thought it was better to rework and make technologies more objective.
Currently we had 4 technologies, two for infantry and two for cavalry. All give armor against pierce and hack, apparently wrong reasons, crush is out.
What the patch does is divide the technologies into pierce + crush for one type and hack armor for another, Both affecting cavalry, infantry and elephantBoth affecting soldiers.
That way the player is free to choose the best type of technology for the moment.
Value of hack armor is less than pierce and crush as it protects against only one type of damage.
Cost must certainly be discusseCost are lower compared to the current values, but an auto value of metal, only wood shiels escapes the rule costing only wood.
Icons according to the description.
I plan to individualizechange the techs attack also to just 4 techs of the attack too on swordsame format, two for melee soldiers and two for ranged soldiers, spear/pikeusing description of close combat trainig and ranged combat training, archercosting high food and wood (stone for ranged) and not metal, etcto compensate the high cost of metal armor.
EDIT
Crush armor removed.
