A plain basic eyepatch or it is too modern?
Btw i can make this facemask but i belive it will be only applyable to your mod. IIRC there was a rome mask helmet but idk if it was for Millenium AD or Imperial romans?
So currently it looks a little like this:
Hoplites start with +2 Crush resistance and +1.5 Hack/Pierce but 5% slower walk speed.
P1 Techs
Hack resistance: "Soldiers +0.5 hack and +0.5 crush resistance and 1% faster walk speed.",
Pierce resistance: "Soldiers +0.5 pierce and +0.5 crush resistance and 1% faster walk speed.",
P2 Techs
Hoplite tradition: Hoplites -1 of reach resitance but −20% training time, −30% promotion experience, and 5% faster walk/run speed. Citizen hoplites 10% less food/wood cost. While Champion +25 Health.
Hack resistance: " Champions and Heroes +1 Hack and +0.5 Crush resistance, all soldiers 2% faster walk speed."
Pierce resistance: " Champions and Heroes +1 Pierce and +0.5 Crush resistance, all soldiers 2% faster walk speed. "
P3 Techs
Hack resistance: Citizen Soldiers -0.5 hack resistance, all soldiers 2% faster walk speed.
Pierce resistance: Citizen Soldiers -0.5 pierce resistance, all soldiers 2% faster walk speed.
So basically, they non hoplites lose out on 4H/P resitsance and 2 crush resistance for 10% movement speed... this could be rough. Hoplites only miss out on 3/3/2 I think if my math is right
