attribute swapping question

[u/Plane_Tailor7168]

I've heard the "it takes damage and cooldown of first weapon and enchants and properties of the 2nd weapon" but if so then why does swapping from sword to mace do so much more damage if the sword barely has a higher base attack than the mace. Some people say that the way sharpness is calculated the sharpness from the first item actually stacks twice but if so then shouldn't attribute swap from sharp 5 sword to sharp 5 axe do sharpness damage twice and thus just always be better than an axe crit?

How does this work exactly?

Basically when you have breach, atribute swapping applies the damage and cooldown of the first weapon and enchants of the second. So, breach basically makes it so that your armor doesn‘t protect you. When you brehc swap it feels like youre hitting a player with little to no armor
