I am unable to set back the Skeleton summon spell back to the hotbar. I removed it while trying to add the Summon Golem spell. Now the slot is empty and I can only add spells from the Abilities section where these spells are not listed.
If I add a spell from the Abilities section the hotbar expends but I can only select the spells only on the hotbar and the ones above are not reachable with the controller.
Can you help here? I am stuck.
Another note. There is no option to add spells in the Book of the dead section.
Edit: Found the solution in the comments of this thread - DIABLO 4 necromancer cant summon golem
It should be move convenient to set spells on PS4. There is no way I would have solved it without help.
