Skills

Your character's skills represent a variety of abilities, and you get better at them as you go up in level. A skill check takes into account your training (Trained skill bonus), natural talent (Ability modifier), and luck (the dice roll). It may also take into account your Species' knack for certain skills or the armor you're wearing (Armor Check Penalty), among other things.

To make a skill check, roll: 1d20 + One-Half Your Character Level (rounded down) + Key Ability Modifier + Miscellaneous Modifiers + 5 (if you are Trained in the skill)
