The knacks command is a way to customize what a character is really good
at. By creating a knack, you identify a particular type of check where
your character excels: for example, you might identify an area of Faith
lore that your character specializes in with a intellect+theology knack,
or a character who is an accomplished jouster might have a dexterity +
riding knack. The description is generally meant to convey the specifics
of your character's knack and when/why it might be applicable.

Knacks cost {} xp to create, then {} + {}*rank to increase. Each rank in
a knack increases the results of applicable rolls by {} and chance for a
critical success by 1 + half your rank (rounded down).
