What if swords could reflect gaurdian lasers?

The Shield is a powerful tool in combat but it proves ineffective when faced with the sheer number of gaurdian lasers being shot at it.
But what if you didnt have to just block the lasers or hide behind a wall?
The old sword block mechanic was a useful tool for blocking foes attacks before but was thrown away after the shield was added because of the obvios lack of usefulness But what if we readded it? The shield is bulky and blocks most attacks but slow so cant really be used in the ocean without sacrificing much needed mobility in such hostile areas like the ocean monument. so imagen the sword block mechanic being added back as a way to block attacks lightly
like a small shield that blocks a percentage of melee/arrow attacks (obviosly not strong enough to tank Deadly attacks because thats the shields job) but can also reflect gaurdian lasers back at them acting as a focus for multiple beams shooting at you (needing to bee aimed within a certain radius around the crosshair).
it wouldnt be able to reflect elder gaurdian attacks but could give a 50% dmg resistance against it allowing people to attack the miniboss quickly if they have enough armour to tank such a hit multiple times or save someone after mistiming a hit.
Sidenotes - blocking takes away durability very fast.
Reflecting would only work for iron and higher swords.
This could also work as an enchant with 5 levels increasing reflected laser strength
The reflected laser would not have piercing
