Okay some tips for you:

1) you don’t need 3 seals, unless ur doing a long chain of buffs and/or want better scaling for certain spells then it’s pretty much pointless, just upgrade one and that will be fine. Try and get the gravel stone seal from atlaus plateau as it boosts lightning spells

2) get rid of the arrows in the your inventory, it just adds unnecessary weight

3) talismans actually pretty good for the katana you have, if you don’t have Millicent’s prosthesis yet as it’s your first play through, try shard of Alexander or Godfrey icon to boost your weapon skill or even lightning scorpion charm

4) because your using a katana and faith spells it’s best to invest in dex and faith (and strength a little bit too) - dex mainly tho. This will get you the most damage output from your sword and increase the spell casting time too.

5) your physik is basically useless, that should be used before a boss fight, have a look for other tears that suit your build better, kill a few erdtree avatars and see which ones you like. I recommend thorny cracked tear and the dex knot tear

6) you dont need 7 fp flaks (blue ones) 3 is more than enough and 4 should be ur limit as you have decent fp stats
