Samurai Stance Skill (Parry Idea)

Base Duration is 1.00 Seconds
During effect, reflects 3000% of all damage taken in an area
Immune to Stuns during effect
Physical Hits treat Phys Damage Reduction as 30% higher than real value during effect

Could this actually work? of course, i'm no expert in poe numbers so this could be polished further, but being able to build around reflected damage for once would be incredible.
