The F. am I doing wrong?!

I'm currently level 140, using a +25 cold uchigatana, 45 dex and 52 int, and for some reason my damage in these late areas is ♥♥♥♥♥♥♥♥.... Currently banging my head against Mohg, dealing around 300 damage each strike.........

Pretty sure you're supposed to proc bleeds to do real damage in that case. Unless you're using huge STR weapons, most of your damage will come from abilities, ashes of war and procs.

[Sir Latrine de Bretagne]

I'm not that far into the game but maybe you rely to much on a single weapon. Adaptability is power. Get a strike and a piercing weapon, test the other elements and status effects.

It depends on enemy resistances. You're likely hitting things that have cold resistance. I recommend changing the affinity of your weapon to suite the damage you need to do.

This is the weapon I apply frostbite, then switch to rivers of blood to not only cause bleed, but also neutralize the frostbite. I'm applying procs and effects as I should, the problem is.... With every weapon, my damage on normal attack is ludicrous. Malenia was hell, even with mimic +10 she destroyed me... all because I never did enough damage

[Maeros]

He is not immune to frost at all, i've applied it many times. frostbite and bleed (which is ironic how the lord of blood is weak to bleed)

When you focus on status effects with your infusions or special weapons focused on those, you sacrifice raw damage value and scaling in exchange. A large portion of your damage will come from those procs instead. If you wanna do damage with your hits, you need to infuse your weapons with a damage-oriented effect, with your stats Magic would probably be the best bet. Keep in mind that split damage takes a big hit though, especially on late-game bosses, so a respec to either more int-focus and finding an all-magic weapon, or to dex and going keen, would typically net you the highest per-hit damage values. Status weapons are quite good, but you have to be aggressive with them to actually get the procs, since the accumulation fades over time, and if you're not hitting fast enough to proc reliably your total output will be trash.
