dark souls 1: pyromancer, and i got lucky enough on my first playthrough to get the boar helmet and black knight halberd at the first availability and just used them forever. gold hemmed black robe and skirt with stone gauntlets
dark souls 2: my favorite outfit. ruin guardian set, black witch hat, black witch staff, sunlight sword, and like 90 casts of dark orb
dark souls 3: i do not remember a damn thing about this game. i think i power stanced light weapons a lot.
bloodborne: tonitrus, flamesprayer, and augur of ebrietas. i am pretty sure i had a mix of armor pieces at all times. augur of ebrietas can stagger just like a gun and the timing is a little more forgiving. plus, you know, slug blast.
elden ring: jar helmet, crucible knight set, coded sword, brass shield. i used lots of incantations but my favorite was frenzied burst. before i got bestial sling i used the flame of frenzy a lot as well. i got the winged scythe pretty early and used that until i found the sword.
sekiro: ninja.
