It locks you out, yes, and if you ever get one of those at 10th level you lose the benefits of Unliving Paragon.
I'll do my best in that regard, any suggestions specifically to tone it down?
Inherent is so it DOESN'T stack with those magic items and wish spell uses. It also prevents stacking the ability bonuses from the Sources with each other and those from the level 10 ability. I do try to mind when making stuff like this.
If you follow the link you'll see that the Invoker class calls Dark Invocations Greatest Invocations instead. And I meant for the Corpse to use that list. As it is, the Invoker outclasses the Warlock too, and I prefer to use it to Warlock anyway.
Yes it is Class Level, so the casting never gets too high (I think level 3 or 4 at the highest), thouch I could probably change it to Sorcerer casting and still keep it okay.
Also, they only ever get one Greatest Invocation. Sure they get it a lot earlier, but still, it's only one, ever, and they can't change it. I could always change it so that it uses Character Level to determine the Invocations and Spells. A half character level progression should tone it down enough.
Hm, debating that, actually. I want to say yes, but I'm not sure if it would require them taking the feat at the level they gain corpse or not.
No and 0 bloodline levels. They just get the benefits of the bloodlines.
Actually, they get three Major bloodlines (using welknair's bloodlines rather than the official ones since the official ones suck), one for each ability. And they gain the benefits of the bloodline at the level they get the abilities that grant them. They still use their character level to determine the benefits.
If you'll note, the Corpse isn't Undead, it's Unliving, meaning it's more of a Living Construct of sorts. It's not healed by positive or negative energy unless it takes the appropriate source.
Any suggestions for making it better?
Yes, you heal from both Positive and Negative energy, same as being an Unliving Paragon. Grants the same benefit.
True, but it requires GM Fiat to even take it (note the Requirements). That one is mainly meant for Solo games or high power games. As it is, I don't recommend GMs allowing the Willpower source in most normal games unless they know exactly what they're doing.
I do intend to create more sources, the main ones being Psionic, Vestige, and Divine.
Any suggestions for toning down the powerful ones and increasing the power of the weaker ones? Like i said, Willpower is mainly a GM Fiat one, so that one shouldn't be as much of a problem.
I also need ideas for Source Abilities, any suggestions there would be extremely helpful.
Really? It's a single improvement for all of them so it'd just be one column of things you can improve, that's really it.
I'll make one if it'll help, but I don't see it helping much at the moment.
