If they are still standing under the [Sacred Treasure: Extreme Battle Banner], led by the Heroic Commander, they can reach up to 59% damage reduction in the best circumstances.
Of course, military units like the Black Banner Guard and Knights, which are inherently tough and robust, can achieve damage reduction as high as 70%, even 80%! At least Tier Four Black Banner Guard, in full status, have 70% fixed damage reduction.
In such a situation, even high-tier spirit skill bombardment, after undergoing fixed reduction, will see its damage greatly reduced, and then defensive deductions further cut it down. Remaining damage will be minimal.
This ratio even surpasses the hero's 50% damage reduction.
The hero's 50% reduction is quite common; many have seen this reduction ratio on various skills or traits and have a very intuitive impression.
