Honestly don't remember. I think I used magic once. Last playthrough was a 40/40 quality one, as usual. I remember it being my most thorough yet. Learned to pin down every crystal lizard in that stonefang pit. Dressed a couple of times as Biorr but with an actually useful bow. Killing the blue dragon with 10 or 20 shots was cathartic.
Biorr's ultra greatsword was fun as hell. It's probably one of those things that people would consider as "jank" after Dark Souls. The attacks are unlike anything that came after. One handed, it's faster to use R2->R1 and reversed when two handing. I'd say it's only "janky" because its eccentricities were never refined by its successors. Since DaS, ultra greatswords are just beefier greatswords moveset-wise. Still fun but not as unique.
The last thing I remember doing was messing around with character and world tendency to get colourless demon's souls for my penetrating sword. That's another fun one. It's surprising how fun unique/boss weapons are. They usually have an interesting mechanic and sometimes stat scaling. Ironically, having the basic weapon moveset makes them more intuitive than the "press R2 for flashy attack" you'd usually get in later Souls.
I think I started manipulating world tendency at the endgame when everything was pure white. Sudoku until (pure?) black, find the bug, get the soul, kill black phantoms for loot and to go back to white. Didn't get back to pure white if I remember correctly. Just one more boss kill which required the next NG+. I remember now reminding myself to do this before killing the last boss of each area so I can get back to PW.
I also tried farming pure bladestone for some reason. Don't remember if I got one.
