They count as turn undead attempts and spontaneous healing so they have can cleric feat abilities. Also many casters utilize incorporeal type abilities for defensive purposes.
They have 6 base except for level 9 which is 5 not including bonus spells, that is good actually. Also you are a warlock you have a consistent back up of powers to rely upon whether eldritch blast, invocations, or UMD, plus decent hit die, two good saves, and skill points. What more do you want? I don't see a problem of versatility and sustainability here compared to other people.
Okay here is how it goes, when preparing spells you send out your spirit guide to make the spells known table then you choose how many you want to put in for spells per day. You have the advantage of spontaneous casting in that you can lose one of equal or lower level if you already casted it or don't have it. Unlike a spontaneous caster you don't have increased casting time and this spells known list can be recreated each day when your prepare spells. So, you have the repertoire and speed of a prepared caster while still being able to be flexible for the day.I was looking the table on the next page that says 3 spells per day (I didn't read it thoroughly enough), the spirit shaman looks really good, I am curious how her spell casting works:
Does she know ALL divine spells and picks a list of spells to prepare and then casts from that list? (does that make sense)
EDIT: I have spotted two problems, most of the higher levels class features are...useless unless we fight ethereal enemies regularly (which I doubt we will be) AND how exactly does one justify being a Warlock/Spirit Shaman (they seem opposed classes)?
There are ways to get arcane but that is Faerun's favorite magic goddess Mystra and her minions with that sort of stuff. Oh I just saw the uses a day and that it functions somewhat similar, but it doesn't say it actually. You could ask the DM to see if he would let it.OK, Fey-Warlock I get but a Fey-Hellfire Warlock stretches the imagination a little
and OK I don't know if many monsters will be Ethereal but I like the Spirit Shaman and the Recall spirit helps when the unfortunate happens (everyone dies at some point) and there's a feat about gaining your spells from an alternate source, is there some way to get Arcane spells (not needed but it would be fun)
Is there any spells that would use the "Guide Magic" ability? (I don't know that many spells off by heart, most are Arcane)
EDIT: I don't really like the Bard's style of play
How do they count as Turn Undead and Spontaneous Healing? (I must have missed that)
Warlock//Dragonfire Adept!!!tbh, I want the ability to deal the same damage on turn 700000 of an encounter/adventure as I do on turn 1...
