TV to Tabletop: One Piece

One Piece is a long-running manga-turned-anime-turned-hit-Netflix-series! It tells the story of Monkey D. Luffy, a young man whose dream is to become the pirate king and find the fabled treasure of the previous pirate king—the One Piece.

One Piece is full to the brim with weird, over-the-top action and ideas. If your 5E game is deadly serious, One Piece might not have too much to inspire . . .  but then again, it might! Check out these adaptations taken from the show for 5E (and the Tales of the Valiant RPG) and see what sparks for your game.

New Magic Item: Devil Fruit

Devil fruit is a rare fruit that confers a supernatural power to the one who eats it. Each devil fruit is unique, both in appearance and in the ability it grants. Devil fruits don’t grow on any known tree, but rather seem to manifest spontaneously. When someone who has eaten a devil fruit dies, it is said that the fruit reappears elsewhere in its original form, ready to grant its power to a new eater.


Wondrous Item, Rarity Varies

This intensely colored fruit has a distinct swirling pattern on its skin. This fruit comes in three types: logia, paramecia, or zoan. When you eat the fruit, you gain the features described in that type of fruit, but you lose any swimming speed you have and have disadvantage on ability checks made to swim. Eating more than one devil fruit immediately kills you.

Logia (Very Rare). Eating a logia devil fruit changes your body’s physiology to be aligned with a specific substance chosen by the GM, such as mud, smoke, lightning, sand, darkness. As a bonus action, you can change your body to take on properties of that substance, gaining all of the following features. You can remain in this form for up to 4 hours, all at once or in shorter bursts, each one using a minimum of 1 minute from the duration. You regain all expended time when you finish a long rest.

  • Amorphous. You can move through a space as narrow as 1 foot wide without squeezing.
  • Incorporeal Movement. You can move through other creatures and objects as if they were difficult terrain. You take 5 (1d10) force damage if you end your turn inside an object.
  • Substance Attack. When you hit with any weapon attack, you deal an extra 1d6 damage of a type associated with your substance. For example, if your substance is ooze, your attacks might deal extra acid or poison damage.
  • Substance Form. As a bonus action, you can take on a form similar to your associated substance. You retain your game statistics, but your body becomes less substantial. Your skin changes in color and appearance, resembling the substance associated with the devil fruit you ate. You choose whether your equipment falls to the ground in your space, merges into your new form, or is worn by it. Worn equipment functions as normal, but the GM decides whether it is practical for the equipment to move with you if you flow through particularly narrow spaces. Your substance form lasts for 10 minutes or until you dismiss it (no action required), are incapacitated, drop to 0 HP, or die. Once you use this form, you can’t do so again until you finish a long rest.
  • Substance Resistance. You gain resistance to one type of damage associated with your substance, such as acid or poison for an ooze substance, necrotic for a darkness substance, or bludgeoning for a mud substance.

Paramecia (Uncommon). The most varied of all devil fruit, each paramecia grants a power similar to a spell. Powers granted by paramecia typically alter your body, allow you to manipulate your environment, or allow you to generate a substance, such as wax or poison.

When the GM adds a paramecia devil fruit to the game, the GM decides which 3rd-level or lower spell is bestowed upon the eater by the fruit. When you eat the fruit, you either gain the effects of that spell permanently, as a feature you can activate as an action and deactivate as a bonus action, or as a feature that, once expended, you regain when you finish a long rest, at the GM’s discretion. These spells are typically of the abjuration, conjuration, or transmutation schools, though any 3rd-level or lower spell can be imparted to the eater of a paramecia devil fruit.

Legends exists of more powerful paramecia devil fruit that grant abilities equivalent to 4th-level or higher spells, but these are rare or even very rare.

Zoan (Rare). Eating a zoan devil fruit changes your body’s physiology to be aligned with a specific animal, much like a lycanthrope. The GM chooses the lycanthrope, but you gain all the features of that lycanthrope when you eat this fruit, except you can’t infect others with lycanthropy. Such lycanthropes include werebear, wereboar, wererat, weretiger, and werewolf, or more exotic forms of lycanthropy, such as werecrocodile (see Tome of Beasts 3).

New Weapon: Cat Claw

The captain of the Black Cat Pirates, Kuro of a Hundred Plans, is a well-rounded man. A master strategist and superhumanly fast, he’s a real catch . . . except for being a remorseless killer.

Kuro’s signature weapon is his cat claws, two furred gloves with a long blade at the end of each fingertip. This wild weaponry is probably based on a Japanese ninja weapon, neko-te (cat’s claws), which consisted of a glove or sometimes just a fingertip band with a short blade extending from each finger.

Cat Claw. A shortsword blade protrudes from each finger of this black, furred glove. While wearing it, your unarmed strikes deal slashing damage, instead of bludgeoning damage, and you can’t pick up or use any objects.

New Talent: Three Sword Style

The iconic swordsman, Roronoa Zoro has a specialized style of fighting with three swords. Don’t ask a ton of questions about that. Just go with it.

Note: In the Tales of the Valiant RPG, what were formerly known as “feats” in 5E have been renamed as talents. For compatibility purposes, you can use them interchangeably, but talents are rebalanced and improved for ToV.

Talent: Three Sword Style

You master the art of fighting with three light weapons, one of which is wielded between your teeth, gaining the following benefits:

  • You gain proficiency in the Athletics skill.
  • You can draw or stow three one-handed, Light melee weapons when you would normally be able to draw or stow only one.
  • When you take the Attack action with a Light melee weapon in each hand, you can also (somehow) use a bonus action to attack with a third Light melee weapon held between your teeth. If you use the weapon in your teeth to make such an attack, you have advantage on the attack roll. As with normal Two-Weapon Fighting, you don’t add your ability modifier to the damage of the bonus attack from the weapon in your teeth, unless that modifier is negative.

    A J. Quick Pirate Kingdom Sheet (‘Castles and Crowns’) might be a nice addition to this…
    …’ piece.’

  2. I have had ideas for a One Piece campaign for a very long time,the physics of the Grand Line, log-poses, and all the wacky islands would be very fun to play in. One of the things that I had been struggling with is how to properly add Devil-Fruits. I had thought of some good ideas but this is much simple. I will be using this for sure!

    1. There is a fan-made adaptation of 5e to One Piece out there, with a player and dm book and an encyclopedia of devil fruits. It was created on Homebrewery by Redditor OneWorldHD and is called “Dungeons & Devil Fruits”. Look it up, I think this is what you need.
