Blade Armor has undergone several adjustments in its history, with the most recent buff significantly altering its functionality.

Previously, Blade Armor's Unique Passive reflected damage equal to 25% of the enemy's physical attack damage, while also reducing their movement speed by 15% for 1 second upon damage reflection. It provided a solid counter against basic attack-dependent heroes, but its effectiveness was limited compared to other defensive items.

However, with the latest buff, Blade Armor's Unique Passive now deals physical damage equal to 50% of the incoming damage plus 35% of the hero's physical damage to the attacker. Additionally, it applies a substantial 30% slow effect for 1 second upon activation.

These changes represent a substantial increase in Blade Armor's offensive capabilities. Not only does it reflect more damage back to attackers, but it also inflicts a significant slow effect, making it much more impactful in both duels and team fights.

Overall, the recent buff has transformed Blade Armor from a niche defensive option into a potent offensive and defensive tool, significantly increasing its viability and potential impact on the battlefield.
