Dacian Falx vs. Roman Helmets & Armor

[Magnus]

Regardless of how good of shape the Dacians were, the evidence points to defensive adaptations because of a specific weapon. The only weapon unique to the Dacians was the Falx. Not spears, axes or swords. The Romans had faced those for centuries, with no adaptations to their helmets. So the only new stimulus, was the Falx. All roads seem to lead to the Falx.
