When a target had no barrier or shield protecting them, their health and durability would both be considered a kind of "boundary"!
That meant Qin Feng's attacks against a target's health and durability would also benefit from the 400-fold damage amplification!
Of course, what mattered most was combining this with Qin Feng's world-breaking grand authority!
Originally, the World-Breaking Sword's normal attack damage had certainly been much lower than Qin Feng's own burst damage.
But after acquiring the world-breaking grand authority, any attack Qin Feng made against any barrier or shield would deal true damage equal to 15% of its maximum life/durability, ignoring defense and damage reduction!
Factoring in the 80% bonus damage against shields that this Primordial weapon itself also provided, that worked out to 27% true damage per attack...
"Doesn't that mean I only need four strikes against any being?"
"Or even... just one?"
After all, Unbreakable Boundlessness itself also provided a 400-fold Damage Increase against shields!
Could this Damage Increase apply to true damage?
He quickly found a minor monster to test it on...
The result showed that the true damage dealt to health was indeed 27%, unaffected by Unbreakable Boundlessness's 400-fold Damage Increase against shields.
Even the Damage Increase against shields from other sources on Qin Feng had no effect on this true damage.
Ultimately, this true damage only benefited from the World-Breaking Sword's 80% Damage Increase against shields.
Qin Feng guessed that this was an inherent rule of Godforsaken Game itself. Otherwise, he could easily stack this true damage to several hundred percent, letting him kill anyone with a single strike and leaving no room for resistance...
Even so, this talent was already terrifying enough.
Even Qin Feng found it quite unexpected.
This world-breaking grand authority had actually not unlocked a talent that let him stack
