Back in 2014, I ran a 4th edition D&D game set in Adventure Time‘s Land of Ooo. I used a fantastic Adventure Time homebrew mod of D&D 4e, by Bloodghost, to run the game. Last week I wrote about new races (species) for an Adventure Time campaign in 5th edition. This week I’ll be drawing from Unearthered Arcana, D20 Modern, Modern Magic and the 4th edition homebrew along with providing my own ideas to look at which classes fit an Adventure Time campaign and 2 new homebrew options you can use in any D&D game.
Watching Adventure Time isn’t required to play in this setting, but it really helps. Any of this material could be used in your own homebrew setting or to get started on playing a game in this setting.
I’ll be breaking this down into four parts and releasing another chapter each week.
- Part 1: Species (Races)
- Part 2: Classes
- Part 3: Alignment, Feats, Weapons & Equipment
- Part 4: Magic Items & Spells
- Part 5: Traps, Hazards & Monsters
Pendleton Ward, the creator of Adventure Time, often mentions how Dungeons & Dragons is the biggest inspiration for the show.
“Well Dungeons and Dragons is probably the biggest inspiration. When I am working on it, it feels like I am running a campaign of D&D. I am just writing stories I would want to play over a table with my buds.”
– from an interview with Pendleton Ward at Geekadelphia
It’s easy to see this inspiration as so many aspects of the show and characters even have roles such as being a wizard, warrior or princess. Yet, the show doesn’t take place in a traditional fantasy setting and the traditional D&D classes don’t all match up perfectly. That being said, I don’t think rewriting all the classes is needed, some simple tweaks will let nearly any option from the Player’s Handbook work in the Land of Ooo.
The biggest obstacle to playing 5th edition classes in an Adventure Time setting is that divine magic isn’t strongly represented in the show. That being said, there are a number of cosmic level characters to draw from if you wanted to create a pantheon such Cosmic Owl, Death, Party God, Grob Gob Glob Grod, Glob and Prismo.
Clerics: Allowing clerics that take a new Medic Domain could work, but I think reflavoring the class as a “new” class called Medic fits the world better. Another option would be to create a Healer arcane tradition using some of the cleric spell list, especially those found in the Life Domain. If you really want to play a cleric draw your power from placing faith in Glob, Party God or another cosmic character.
Paladins: Finn is a knight who has sworn an oath to protect the Candy Kingdom, but he doesn’t exhibit divine powers he can control. Creating a new Paladin oath could work too, but I would recommend leaving Paladins out of the class list. If you really want to allow paladins, try out fun options. One option could be to have a paladin fight for the right to party, by worshiping Party God and taking an oath to party hard.

Clerics work better as Medics in Adventure Time. These are notes on how to simply reflavor the Cleric class with the Life Domain as a Medic for Adventure Time.
Cantrips, Spells & Spellcasting Focus
- Nearly any cleric cantrip or spell can be used as is, but you’ll need to try to reflavor it be more medical than divine – and some are a better fit than others.
- The spells should be the effects of using doctor instruments like syringes full of healing fluid and nebulizers for spraying aerosols to distant allies.
- Rituals should be similar to a doctor researching a medical problem for an answer.
- I would recommend using a medical instrument of some sort as a focus or a lucky charm.
Turn & Destroy Undead
- A small change to Turn Undead this…
“As an action, you speak a few words to an undead to remind them that they are very sick and should go home and take a nice long rest.”
- A small change to Destroy Undead to better fit Adventure Time skeletons and zombies…
“When an undead fails its saving throw against your Turn Undead feature, the creature is instantly returned to health (zombie) and goes home to sleep it off or returns to its grave (skeletons), if its challenge rating is at or below a certain threshold…”
- Rename to Medical Miracle
- “Beginning at 10th level, you can call on your faith in medicine to help you pull out a medical miracle when your need is great.”
- All references to deity should be replace with faith in your training, etc.
- “Your DM chooses the nature of how this miracle will play out.”
- A Medic is really just a Cleric without the divinity and should take the Life Domain.
- Rename Divine Strike as Anatomical Precision and “At 8th level, you gain the ability to use your expertise in the field of anatomy to direct your weapon strikes at the weak points of your enemies…“
Scientist – Arcane Tradition
Scientists are super brainiacs who spend all day hiding in a lab, until they are dragged out on an adventure. Magic is part of everyday life in the Land of Ooo, but so is science. Scientists don’t cast spells using magic. Scientists use the scientific method to conduct experiments and invent devices to create wondrous spell like effects using science. As as stated in Clarke’s Third Law (“Any sufficiently advanced technology is indistinguishable from magic”), the abilities of scientists are quite similar to other wizards, but their source is not magic, but knowledge of the universe.
Scientists are played just like a Wizard, but spell slots are like available brainpower and if you consume them doing science stuff, then you need to rest up your noggin.
This homebrew Scientist Arcane Tradition borrows heavily from the Unearthed Arcana Artificer that is currently available for playtest.
Create Chemical Elixir
Starting at 2nd level, you can conduct experiments to produce useful chemical compounds that work in the same way as potions, but are called Elixirs. You spend 10 minutes with your portable chemistry kit and expend a spell slot to produce an elixir from a formula you know (see list below). Once you have expended a spell slot to create the elixir, you cannot regain that slot until it’s consumed or after 1 week, at which time the elixir loses its potency. You only have enough beakers to store three elixirs at a time, so creating a new, fourth elixir requires you to consume or destroy one of your three already existing elixirs.
The spell slot you expend determines the type of elixir (identical effects as related potion) you can create. See chapter 7 of the Dungeon Master’s Guide for complete rules on potions and information on each potion.
|Elixir Formulas Known (Potions)
|Diminution, Growth, or Healing
|Invisibility or Greater Healing
|Speed or Superior Healing
Create Simple Device
At 2nd level, you can also tap into your knowledge to create a simple device. You can use your Arcane Recovery ability to develop this device using science instead of regaining your expended spell slots (or brainpower).
You must finish a short rest, then spend 10 minutes to create a single-use device which is able to “cast” one “spell” chosen from those you know. Subtract the spell’s level from the total levels worth of slots you regain using Arcane Recovery. This reduction to your Arcane Recovery applies until you use the simple device and then finish a long rest. Once used, the simple device is useless except for recycling the raw materials for your next device.
Charge-Up Weapons and Armor
Beginning at 6th level, you can charge-up weapons and armor using your knowledge awesome knowledge of alloys and science. You can spend 1 hour (10 minutes for something that has previously been charged-up) tinkering with a mundane weapon, suit of armor, shield, or bundle of twenty pieces of ammunition, and expend a spell slot to power it up. Charged-up items are tricky and needs lots of maintenance, so they only retain their enhancement for 8 hours or until used (in the case of charged-up ammunition). You only have enough rare materials to charge up one item at a time; if you charge up a second one, the first immediately loses its potency. Once you have expended a spell slot to create such an item, you cannot regain that slot until the item is stripped of its enhancement. Charged-Up weapons and armor should be considered as magical as magic weapons and armor for the sake of rules.
The spell slot you expend determines the type of weapon, armor, or shield you can charge up.
|+1 ammunition (20 pieces)
|+1 weapon, +1 shield
|+2 weapon, +2 ammunition (20 pieces)
Master’s Degree of Science
Starting at 10th level, you have developed enough raw materials that you can now power-up a second weapon, suit of armor, shield, or bundle of ammunition using your Charge-Up Weapons and Armor ability. You can’t attempt to power-up a third item without stripping and powering down one of your other 2 items first.
- expanded your chemistry set and can create one additional elixir using Create Chemical Elixir
- found enough raw materials to create one addition device using Create Simple Device
Doctorate Degree of Science
On reaching 14th level, your mastery of the laws of nature allows you to produce a variety of inventions. You can create a single item chosen from Magic Item Tables A and B in chapter 7 of the Dungeon Master’s Guide. It takes you 1 week to produce such an invention, and you must rest your brain for 1 month before you can be inspired to invent another such item. You must come up with a vague scientific explanation for how you created your invented item and how it works. The item should be considered magical and will have identical effects as the matching magical item for the sake of rules.
