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