Alrighty, the class of Crabs is in session!
When making your character, you have to decide your race, class, and other. I'm going to go over these three things because they affect your rolls. The other things, while useful, are thing that don't really need any info, unless you would like me to.
Race is well, race. I chose the shota animal people option. The (2d6) around it means that when I make a roll relevant to my race, I roll two six sided die.
Class is kinda the same thing. Sure you can just choose berserker or mystic, you can also personalize it like "Family taught giant axe berserker" or "Mystic of the hidden order of (insert deity here)" The 4d6 here will be used often during combat.
Other is the most broad, which also means the hardest to choose. It can be ANYHTING you want. A special weapon, a secret organization you are affiliated with, it could also just be a second class! (albeit weaker at 3d6)
You also get 3 rerolls. Don't like one of the dice you just rolled to do something cool? Use a reroll and reroll it! Did Atmo's roll to "mutilate your character" come out extremely high? Make HIM reroll!
Also, since we are kinding adding a tale to our character through our history, you get to add a single die to Race, Class, or Other. That's basically my explanation and understanding of the character creation, feel free to ask for more explanations!
