Rules-Lite Samurai Game Using d20

Here is a basic rules-lite system for playing as magical samurai in the Legends of the Five Rings universe:

Attributes:

    Strength: Physical power and ability in combat.
    Agility: Speed, flexibility, and dexterity.
    Intelligence: Knowledge and understanding of magic and the world.
    Spirit: Willpower, determination, and spiritual power.

Skills:

    Bushido: Your skill in the way of the warrior.
    Iaijutsu: Your skill in the art of drawing and striking with a sword.
    Kenjutsu: Your skill in sword fighting.
    Kendo: Your skill in armored combat.
    Ninjutsu: Your skill in stealth and subterfuge.
    Shugenja: Your skill in magic and spellcasting.
    Tea Ceremony: Your skill in the traditional Japanese tea ceremony.

Equipment:

    Katana: A traditional Japanese sword.
    Wakizashi: A shorter sword, typically worn as a companion to the katana.
    Yumi: A traditional Japanese longbow.
    Ya: A traditional Japanese arrow.
    armor
    Magic scroll

Combat:

    When engaged in combat, players roll a d20 and add their relevant skill or attribute to determine success.
    Players can use spells or abilities to gain bonuses to their rolls.
    If an opponent is wounded or otherwise at a disadvantage, players can choose to perform an iaijutsu strike for an automatic hit and potentially an instant kill.

Resolution:

    Players roll a d20 add their relevant skill or attribute to determine outcome.
    GM sets a Difficulty Class (DC) and if roll + skill/attribute >= DC player succeed otherwise they fail.
    If players succeed they achieve what they intended if they fail they might achieve it but with some complications or not achieve it at all.

Note that this is a simple example and would need to be fleshed out more to make a full functioning game. Also it would be better if you familiarize yourself with the Lore of the L5R.
