Stats: After becoming an adventurer and learned different skills, Kazuma had two high stats:
Luck: Kazuma has an extraordinarily high luck stat, so high that even Luna was surprised. However, she claims that its numerical value isn't really essential to an adventurer. The only person Kazuma has ever lost to in a game of rock-paper-scissors is Eris, the Goddess of Luck. During his gambling streak in the nation of Elroad, Kazuma was able to win enough money to temporarily put a casino out of business. Though frustrating and unpredictable in the short-run, most things end up turning out well for him, no matter how many times he makes the same mistakes.
Intelligence: His statistical intelligence is decently high, one of the highest out of his entire party, behind Megumin. In practical use, he is very cunning and sharp, often employing the usage of unorthodox tactics. This makes a powerful combination with his luck stat; his ideas tend to be good ones.
Skills and Magic: Kazuma belongs to the Adventurer class, and as an adventurer, Kazuma can learn and use skills and magic spells of any class. He can also level-up easily. After venturing into the world's hardest dungeon, he learned many other skills on top of the ones he had prior due to having an insane amount of skill points:
Thief-Class:Bind: Binds a target in rope provided the user has a rope on them.
Disarm Trap: Allows the user to disarm any traps in their path.
Trap Detection: Allows the user to detect any placed traps in the area.
Enemy Detection: A passive skill that notifies the user of monsters or enemies nearby, with a ping.
Lurk: Makes the user difficult to detect while in the shadows, though it does not work when the user is out in the open.
Concealment: A superior version of the Lurk skill which grants the user invisibility for a very short span of time.
Escape: Allows the user to escape a situation if it is possible.
Steal: Steals an item from the opponent. Higher luck results in a more valuable item stolen. Due to this, Kazuma often unintentionally (or intentionally) steals the opponent's underwear. In episode 21, he uses it to punish two ladies from the guild who hurt his feelings; he stole their panties.
Knight-Class:One-Handed Sword: The One-handed Sword skill raised proficiency with one-handed swords.
Wizard-Class:Tinder: Summons a small fire in the user's hand or fingertips.
Create Earth: Summons rocks and sand on the user's hand.
Create Water: Summons water on the user's hand.
Wind Breath: Blow a small amount of wind from the user's mouth.
Freeze: Freezes water, or any objects.
Fireball: Generates a ball of flame that can be thrown at a target.
Lightning: Generates a bolt of lightning.
Flash: Creates a bright flash that blinds the opponent.
Unlock: Allows the user to open up any lock.
Teleport: Teleport allows Kazuma to teleport objects or people to "marked" locations, which are places he has already visited. Kazuma can only maintain three markers at a time meaning there are only three places he can teleport to, one of which is the boss room of the deepest dungeon in the World. Kazuma can also use a random teleport, removing the need of a marker but in turn transporting a person or an object to a random location in the world.
Explosion: Summon forth a devastatingly large incendiary detonation.
Undead-Class:Drain Touch: A skill normally only processed by the undead, Kazuma learned this skill from Wiz and can use it to drain mana from others as well as give. It can only be used through direct contact and drains mana very quickly, so Kazuma is able to utilize this skill offensively in order to render opponents unable to move once they are drained of mana. Drain Touch isn't very effective against opponents with high endurance, such as Darkness and Mitsurugi, who can usually retaliate before being drained.
Archer-Class:Bow: A passive skill that allows for the usage of Bow weapons.
Snipe: Powerfully fires a single arrow with accuracy depending on the user's luck.
Farsight: Allows him to see far into the distance and improve the user's vision overall.
Monk-Class:Auto-dodge: Allows the user to dodge any attack autonomously. Activation is dependent on one's luck stat.
Ranger-Class:Trap Creation: Increases the power and activation chance of any trap.
Creator-Class:Create Earth Golem: Summons golems formed from solid, clay, or mud. The size, strength, and operation time of the golem varies on how much mana the user uses.
Priest-Class:Heal: Heals the user or an ally. It can also be used to Purify The Undead.
Assassin-Class:Deadly Backstab: Kills enemies in one hit if conditions are met. The user being undetected is one of these conditions. The success rate is based on luck.
Dark Stalker Class:Lip Reading: As long as Kazuma can see someone's mouth he can understand what they are saying. It is often used in combination with his Farsight ability.
Eavesdrop: The ability of secretly listen to a conversation from a distance.
Chef-Class:Cook: He learned the ability of cooking with the idea of having a calm life and even opening a restaurant if he had the chance, he used this ability to help in the Axis Cult festival, making several dishes from Japan to attract customers.
BlackSmith-ClassSmithing: Kazuma uses his smithing ability to great effect by inventing products from Earth, such as dynamite, condoms, lighters, and kotatsu, and selling the intellectual properties of these products for profit, as well as repair armor made out of adamantite.
