I read somewhere that spearmen have an initial, passive attack against cavalry while they are stationary. This appears to be triggering even when the spearmen are stationary while constructing siege like a battering ram. Cavalry run up to attack the spearmen, which have their backs turned, focused on the ram. Yet the spearmen inflict damage to the cavalry when the cavalry make contact.
@Heftydogg I believe the passive you are referring to is that when a Spearman is targeted by a Cavalry charge attack, they brace and perform a Spearwall attack.
I’ll make sure the team takes a look at the expected behavior here. Appreciate the report @Heftydogg!
