Okay, as a reply so people can see it more easily, here's a list of how powerful things are, from most to least.
Greater Gods (GG) (PCs) - A single god can, by itself, take on anything else 1 on 1 and win. Might be difficult, but they will.
Devils(PCs) - Two devils working together can defeat a Greater God.
Lesser Gods (LG) - Two working together can beat a devil, three can match a Greater God. Greater Gods can make Lesser Gods, though it takes a hefty chunk of power. They have mind sof their own(I say what they'll do) but usually help you, if only because your domains and goals usually align, and GGs are often more capable and knowledgable. They have one or two domains of your choosing(1 major or two minor)
Faery Lords(FL) (PCs) - Two can take on a devil and be even, or beat an LG, it takes at least five to beat a GG.
Demons - As LGs are to GGs, Demons are to Devils. Two can match an FL. One concept.
Angels - Will do what their god says. Only made by GGs. Have characteristics dependent on their god. Two to three to beat a demon.
Faery Court (FC) - The more powerful Fae, but not as powerful as the lords. Similar, but not equal, to LGs for GGs(have one idea, not two). They flock to you instead, so you'll often have quite a few once you get your power base established, but beware! for the Fae are envious and may seek to overwhelm you. Takes at least 5 to beat a FL. Two can beat an angel.
Imps - As Angels are to GGs, Imps are to Devils. Three to beat an FC.
Lesser Fae (LF) - Actually about the same power as Imps, but takes four to beat an FC.
Human Magic Users - Depends on their power, but most are weaker than Lesser Fae. None are stronger than Faery Court. Ones supported by the Powers That Be are more powerful, of course.
There are exceptions; anything with a war or fighting domain is, in a straight fight, typically 1 tier higher(a Demon with the concept of Battle will beat most Faery Lords).
Also, a few unique powers. Devils and Demons can possess people, Both Celestials(GGs, LGs, and Angels) and Fiends(Devils, Demons, and Imps) can appear in dreams. Gods can make prophets. Fae(Lords, Court, and Lesser) can interact more easily with mortals; anything they do with them directly is far more likely to be successful. They're the most relatable of the classes to these people. It's usually a good idea to put aside your grievances and get a Fae on your side for that reason. Of course, Fae are wily, and only a Lord is likely to see any reason to do so...Gods find it very difficult to perform miracles beyond prophet, race, or domain-related ones. Don't try and put out the sun if you aren't a god of darkness, the sun, or fear.
Will update turn in a few minutes. One more thing. Evil gods don't get many worshipers. Humans don't like you. So be careful.
Finally, when posting actions, try to post your god's name, so I can look through the massive wall of posts more quickly. Speaking of, who wants an OOC thread so you can talk this stuff without me going GAH I CAN'T FIND MR. EXAMPLE'S POST! :p
