Adding abilities question

[jooozek]

you should instead buy a kalicizma ( カリシズマ ) with some good affixes and grind it to unlock potential and then grind again and keep extending as long as you met the stat requirements
wouldn't bother with anything better till you at least get to level 70
edit: actually forgot just how high dex requirements go up for katanas, you likely won't be able to equip the levels where they at least mediocre unless you are building a dex mag which you shouldn't so just affix it - to make a 3 slot affix you first need to 1 slot affix it, then 2 slot affix if you succeed and then 3 slot etc., you can use fodders with more slots than the base item you want to affix
