yes armor is 1% effective upon hp.
sorry i took a while to reply.
Ld is severely better than old Lw against actual armor tho.
and its actually slightly better late against people with no armor with 1 hp item.
giant slayer -> Ld isnt necessarily a bad idea.
but the second that that mundo builds a dead man's his health becomes like i dont know how much armor but approximately 160% of what it would be in terms of raw damage.
so 35% of that dead mans .35 x .6 = .21 so 21% of his effective health out of the 60% he bought. vs a giant slayer which is 1.1 x your ad
which at that point in the game your ad is only like 160-200 tops so you're like 220 damage aa's as opposed to something like lw
where u have 190 damage aa's but his effective health is only 139% instead of 160% which on a mundo saves u more aa's than a giant slayer. where as on something like swain where he just builds roa with nothing but health on it giant slayer would be better obv.
