Acrobatics is a Body Skill that represents how well a character can jump, keep their balance, and in general conduct themselves physically with swiftness and grace. Characters with a high Acrobatics Rank tend to be highly agile and well-coordinated, and it reflects in their activities. Gymnasts, parkour practitioners, circus performers, and dancers would all have a high Acrobatics.
Some situations where you might roll Acrobatics include keeping your balance as you shimmy across a perilous ledge, jumping across slippery stones in a river, and dodging out of the way of falling debris from a cave-in or an earthquake.
Athletics is a Body Skill that represents physical training and endurance developed through sports and exercise. Characters with a high Athletics Rank tend to be very active and either spend time training their physique or have physically strenuous occupations.
Some situations where you might make use of the Athletics Skill are when climbing a tree or the side of a cliff in the wilds and when trying to keep yourself afloat in the ocean during a storm.
Combat is a Body Skill that represents training in physical fighting and specialized battle techniques. Combat can represent formal schooling in unarmed martial arts, weapons training, or simply very good street fighting and brawling.
That isn’t to say Combat has no use outside of battles. Opposed Combat Checks can be used for two characters grabbing at the same item or trying to push each other around without trying to seriously injure one another. One can also make use of the Combat Skill in martial arts performances or to break down obstacles with brute force.
Stealth is a Body Skill that represents a character’s ability to hide, sneak, and generally move and act undetected. Stealth is often associated with less than legal occupations, such as thieves and assassins, but characters with high Stealth Ranks could also easily act on the side of law enforcement or as field researchers studying reclusive or violent Pokémon.
While the most common usage of Stealth is to move around unseen and unheard, the Skill also covers sleight of hand tricks and larceny, meaning it is tested when a character attempts to pickpocket someone or pick a lock. Acts of escape artistry and sleight of hand tricks also fall under the purview of Stealth; for example, characters may make use of the Skill to free themselves from bindings or slip out of a trap.
Perception is a Mind Skill that represents a character’s awareness of their environment and attention to detail. Characters with a high Perception Rank have not only honed senses but a trained mind that knows where to look for details others would normally miss.
Perception is tested whenever your character is faced with a situation where they could miss a crucial detail in their surroundings. Some examples of this include finding a carefully laid trap in Team Rocket’s hideout, spotting a Stunfisk buried in the mud, and turning up bloody Pokémon fur and feathers in the corner of a crime scene.
Focus is a Spirit Skill that represents a character’s ability to concentrate on difficult or complex tasks or to work under pain and stress. It can be thought of as analogous to willpower, and characters with a high Focus Rank are often intensely driven and ambitious, or at the least unshakable once they’ve dedicated themselves to a task.
The most common uses of Focus come into play when it’s rolled alongside a use of another Skill to test how well you can concentrate on the other task. For example, it may be a Stealth Check to pick a lock, but if a character was suffering from the painful venomous bite of a Seviper on their hand, they might also need to test Focus to keep steady and concentrated on the task. A complicated maneuver such as jumping into the air, throwing a knife to hit a specific target, then teleporting to a platform mid-air and pulling a lever at an exact timing when landing would also call for a Focus Check in addition to the Acrobatics Check that would be invoked.
