Dark Souls. Originally posted by Senrei: Get rid of any other spells you have on and assign it then. That's only if you have 2 attunement slots available. PlayStation 3. 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). 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+. I was wondering. 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. I have two attunement slots and 2 spells but can only equip one of them.
