no of gray horses * 10 = damage to the unit next it when they get their turn.
E.g. 10 gray horses next to hydras, hydras get their turn -> 100 damage.
But if there are multiple stacks of gray horsies only the highest will count.

somewhere near the end of the combat
20 + 3 (gated) gray horsies near 4 hydras;
they SHOULD deal 23*10*0,76 (demon fl8) = 175 damage
but they DID 20*10*0,76=152 damage
so they completely ignored the 3 gated gray horsies, while they did damage my hydras earlier when they were near the hydras |
