Quickie guide.
The profile format is a collection of concepts that make up your character. Think of it more as a biography than a set of numbers. You might see the wall of text and be scared, but I'd encourage you to ignore it completely right now. Think about what kind of character you want, and we’ll find how it fits later.
Name, race, height, weight, and appearance are pretty simple. You can be a human or a rock man, a skeleton or the descendant of a God's Angel or Demon.
Race:
Strength X, Stamina X, Agility X, Speed X, Endurance X, Willpower X, Intelligence X, Perception X
Strength is your character's physical strength. Stamina is your short term energy, while endurance in your long-term energy and and your HP - how much you can endure. If this is confusing: sprinters have high Stamina, marathoners have high Endurance. Agility affects your Dodge and is akin to Dexterity in other games. Speed is how fast you are. Willpower has to do with will, pain tolerance, and magic; Intelligence is intelligence and wisdom, also dealing with magic. Perception measures your senses, attention, and also has ties with intelligence.
If your character is, say, a Soldier, they probably have Strength and Endurance, while a Mage might have Intelligence and Willpower. A thief would have Agility and Perception. Or whatever you prefer.
HP: 10 + Endurance + 2 HP per level in combat class + 1 HP per level in other classes
MP: 5 + ( (Intelligence + Willpower) / 2) + 2 MP per level in supernatural class + 1 per level in other classes
Huh?
Okay. Steve the Soldier 3/Adventurer 1 and Betty the Witch 3 / Adventurer 1.
Steve: Strength 14, Stamina 12, Agility 13, Speed 15, Endurance 18, Willpower 10, Intelligence 10, Perception 11
Betty: Strength 10, Stamina 9, Agility 10, Speed 10, Endurance 14, Willpower 17, Intelligence 20, Perception 14
Let's start with Steve.
10 base hit points + 18 endurance + 6 HP from Soldier and 2 HP from Adventurer = 36 HP
5 base magic points + 10 Int/Will ( (10+10) / 2 ) + 2 MP from Adventurer and + 3 MP from Soldier = 20 MP
Adventurer counts as both combat and supernatural.
Betty.
10 base hit points + 14 endurance + 2 HP from Adventurer + 3 HP from Witch = 29 HP
5 base magic points + 19 Int/Will ((20+17)/2) + 2 MP from Adventurer + 6 MP from Witch = 32 MP
Makes sense?
Level: You start with Adventurer 1, and pick three more. You can be anything except a Wizard (try "Ritual Mage") Saint, Defender of the Faith, or Elder Mage. It can be anything you want, as long as you can define it. In the predefined classes, there is a distinction between "learned" and "inherent" classes, such as "Soldier" versus "Warrior" or "Ritual Mage" versus "Sorcerer".
Virtues and Flaws. Here's where you define your character. What makes them real? What are they good at, what are their flaws? In general, Virtues are positive aspects, while Flaws are negative aspects.
They are defined in strength as "Critical", meaning "It is central to their being and used every single day", "Major" meaning "It is an important part of their concept and is used regularly", and "Minor", meaning "It's a quirk or thing they have that is helpful."
Maybe your character is Happy. Critically happy, in fact; they are always smiling, impossible to insult, and all around the sweetest person around. Or just Major, where they're usually kinda smiling and always ready with a joke. Or Minor, to where they'll just randomly smile and feel happy.
Or maybe it's their identity. Say that Steve the Soldier finds that being a Soldier is so Critical to him that it's who he is, suspecting that he'll live as one and die as one, cheerfully accepting the label, and all in all acting like what you'd expect. Fast forward twenty years, when he has a family and scars, where Soldier is a Minor factor - he always wakes up at the slightest noise, and is spry for his age, but it's not THE thing in his life.
The same applies to Flaws. Here's where details count. Is your character Critically Angry? Are they always going around smashing things? Do they compulsively seek fights? Are they just complete grumpy assholes who are no more violent than the average Adventurer? Is it Racist Angry or Grudge Angry or Seriously, Just Fuck All Y'all Angry? IF they are an Alcoholic, are they just kinda half-buzzed all the time, or do they go on nightly hell-benders and be stone sober in the day?
Critical are 3, Major 2, and Minor 1. You are expected to have between 5 and 7 points of Virtues and Flaws.
As you can see, these can and will change over time. That's how characters grow. Maybe one day the Major Alcoholic decides to quit. Over months of IC struggle, he eventually replaces Major Alcoholic with Minor Recovering Drunk, and gains 1 or 2 Willpower. Or maybe your Happy character sees their sister killed in front of them, and replaces Major Happy / Minor Naive with Virtue: Critical Anger (Revenge) and Flaw: Major Cynic. Or, as what actually happened in game, your character takes a chunk of stone to the head, and permanently gains Critical Flaw: Brain Trauma, while the mixed blood allows him to Choose to become a True Faerie and shed mortality forever, losing a few levels and changing some virtues/feats.
Hobbies are similar. What are your characters hobbies? Do they whittle? Collect stones? Sharpen things? Crochet? Three points. If you want your character to learn more, write about them learning new ones!
Last are feats. Think of them as unique and powerful things only a select few can do. Some people are Tough and gain 3 HP, others are Magically Inclined and have a 25% reduction in cost for any supernatural power. Others can Draw a Straight Line or Do Kinky Things With Their Tongue (please don't select that as a feat, this isn't that sort of game.)
Once you have this, THEN go look at the walls of text. Look at the Gods and pick three. Find the niche for your character and do a backstory; ask thread regulars or just ramble about whatever you like and we'll be more than happy to help.
