I like this question. I really like it, and I appreciate the clarification DarkGod.
I'm going to use my own opinions/experiences/bias to try to flesh things out, but note I'm not a developer or designer. I just find this whole thing interesting as a fantasy construct and want to throw in my two cents
So, for resources (and power sources) so far we've got:
Stamina, Equilibrium (natural)
Mana, Positive/Negative Energy, Paradox, Vim (arcane)
Psionic, Hate (psionic forces).
Stamina represents physical ability, and with proper technique anyone can access their own natural physical ability. Better conditioning will let you do more fancy footwork more often and in a row, and better technique will increase this ability. It's a pretty natural thing to understand as you can imagine it exists in our own reality, and it's ultimately an
internal force
Equilibrium represents the natural order of things surrounding you, and your ability to manipulate it within it's own rules. Ultimately though, you're using your own will to control a greater untapped energy in the lands, which is why I'd say the resource is unlimited but your skill at manipulating more and more of it comes at greater risks of abject failure. While it's a natural skill, it's still an
mixed source force, since you're directing the external with internal will.
Mana represents your own ability to enforce your will on the natural world (by definition unnatural). Ultimately there are limits to the power you can channel, and that powers coming from nowhere but yourself. It's an
internal force.
Positive/Negative Energy represent your ability to channel the latent energy from celestial objects. Their powers wax and wane together, and so share close relationships with each-other. You're controlling
external forces and must find the balance between the two to truly be successful.
Paradox represents the state of reality surrounding you. The more you meddle, the more at risk of forces beyond your control risk unleashing and breaking through unexpectedly, but also the more malleable reality itself becomes to you. Ultimately, it represents your will and ability to manipulate the cosmos themselves, and so its a
external force. You direct reality, and reality makes it so- so long as you can keep it stable enough to stay in existence. Hence why those who meddle and live long times often take some time to stabilize reality around themselves.
Vim represents a corruption of mana and internal forces. Strictly speaking, you're spending the 'soul' or rather more apt internal forces of both yourself AND those affected. Ultimately this makes it an
corrupted force and is why it's popularly considered blasphemy and unwholesome, yet related to the more 'wholesome' arcane- you're using stolen internal force.
Psionic represents instead of physical ability, your mental ability. They are powers latent inside us all but unexercised and waiting to be tapped. They're wholly natural, but still extraordinary as most don't have the discipline inside and focus on an effect, not to mention the technique to wield them. This discipline, focus, and will are wielded to create effects externally, but the power is wholly an
internal force.
Hate represents mental ability still, but instead of discipline tempered focus we're dealing with unbridled focus and ill will. It's considered a corruption of psi power for this reason, and whilst the power is internal ability directed, this ill will requires something external to provide the energy. Ultimately it's a
corrupted force as instead of providing ability through discipline, you're providing affect from malevolence to external beings.
So, for internal forces we've got stamina, mana, psionic. Note that these will all recharge overtime, as they're internally derived and rest can only help. Cool, huh?
External forces include positive/negative, paradox, and equilibrium. Note that each one of these is theoretically 'unlimited,' you can cast over and over and over again ad nauseam- though your ability to wield that much power might not be skillful enough. They all involve some kind of action required to keep such unlimited powers under control, and so you don't rest to replenish them. You act.
Corrupted forces provide some interesting bits though, and are fairly exceptional to the rule. They represent corruption in that they're internal forces twisted around 'wrongly' and grabbing power from other beings. This is why you can't take corrupted forces and do things with them in isolation. Vim is arcane energy gone power hungry, attempting to wield the life of all things surrounding you instead of your own limited potential. Hence the relationship to the charred scar. Hate is undisciplined psionics driving it's focus and energy from malevolence and ill will.
Anyways, I'm sure this isn't perfect or probably even what the developers had in mind but that's what I see and get out of all of this.
