Heightening is an option I suppose but looking there are only 2 spells that can heighten into that slot. I mean spending a 4th level slot to get 6 more hp with false life seems a bit of a waste.
Also where is our create undead spells? The only one close I see is level 2 bind undead.
I guess I don't understand the purpose of necros in PF2. I was making a villain for my campaign guess I'll have to change him. Hmmm.
Thanks for the replies.
Create Undead is a Ritual and not a spell (rituals are after spells and Create Undead is on page 411)
