Ive been playing my first run of dark souls remastered (my first game) and on my knight save ive just got to anor londo on NG+. That's only if you have 2 attunement slots available. My current Level is 12 which i got up from 10 so any guesses on how much more attunement needed for another spell slot? TheDipper (Topic Creator). Dark Souls. . I was wondering. PlayStation 3. I have two attunement slots and 2 spells but can only equip one of them. So you can have 3 phantoms and 3. If you use Dried fingers you can summon more phantoms, but you also get invaded more because slots change. Originally posted by Senrei: Get rid of any other spells you have on and assign it then.
