Introduction: When the Perfect Monster Doesn’t Exist

Sometimes the exact creature you need just isn’t in the Monster Manual. Maybe your players took an unexpected turn, or maybe you’ve imagined something too weird, too fun, or too dangerous to already exist. That’s where homebrewing comes in — and D&D Beyond makes the process surprisingly simple.

In this guide, you’ll learn how to homebrew a monster, build a clean monster stat block, and publish it directly to your campaign. Whether you’re tweaking an existing creature or designing something new, this step-by-step guide walks you through it.

Let’s make a monster.

“If you can imagine a creature, you can build it on D&D Beyond.”

Why Use D&D Beyond for Homebrew?

D&D Beyond is the official digital home for most 5E content. It hosts thousands of monsters, and it also supports an enormous, growing library of homebrew creations made by players and DMs around the world.

Recently, I needed a creature for my Voxels & Valor campaign — a Minecraft-inspired Piglin — and nothing official quite fit. So I built it myself… and it turned out to be one of the easiest homebrew experiences I’ve had.


Step 1: Choose a Base or Start Fresh

Head to:

Collections → Homebrew → Create Monster

You’ll see two paths:

Copy an Existing Monster

  • Easiest option
  • Provides an instant structure
  • Great for re-skinning creatures

Start From Scratch

  • Perfect for something truly unique
  • Lets you define every detail
  • Excellent for complex or custom lore creatures

For this tutorial, we’ll start from scratch.


Step 2: Create the Monster’s Shell

Below is a table you can follow — you can paste this into your post using a Table Block:

FieldValue (Piglin Example)
NamePiglin
SizeMedium
TypeHumanoid
AlignmentChoose any / leave blank
Armor Class12 (Leather Armor)
Hit Points2d8 + 2 (Avg. 11)
Challenge Rating1/8
LanguagesCommon (or one fitting your world)
Strength11
Dexterity12
Constitution10
Intelligence10
Wisdom10
Charisma10

After entering this information, click Create Monster.
This unlocks additional sections like Actions, Traits, Movement, Senses, and more.


Step 3: Build the Stat Block

This is where your creature starts to feel alive.

Armor Class & Hit Points

AC is usually tied to armor or natural defenses.
HP can be entered as a dice formula or a flat number.

Speeds

Most humanoids: 30 ft.
But change as needed — burrow, climb, swim, or fly speeds can define a monster’s role.

Ability Scores

When you enter STR through CHA, D&D Beyond handles the modifiers automatically.

Senses

Add Darkvision, Tremorsense, etc., only if the creature needs them.

Saving Throws & Skills

Optional, but helpful for more advanced or specialized monsters.


If you’re unsure about numbers, copy a similar creature and use its stats as a guide. CR will fall into place once your abilities and actions are added.


Step 4: Add Attacks, Traits, and Actions

This is the most flavorful part of the process.

Actions (Attacks)

Start simple. For a low-CR creature:

Tusks. Melee Weapon Attack: +2 to hit, reach 5 ft., one target. Hit: 3 (1d4 + 1) piercing damage.

Traits

Traits define what makes your creature unique. Example:

Treasure Hunger. The Piglin has advantage on checks to detect gold or gemstones within 30 feet.

Reactions / Legendary Actions

Save these for tougher monsters.
Great for bosses or elite foes — unnecessary for basic creatures.


Step 5: Add Flavor and Description

Flavor brings your monster to life. Consider:

  • Appearance
  • Personality
  • Habitat
  • Behavior
  • Culture or instincts
  • How it fits into your world

The Piglin, for example, might have:

  • Blocky features
  • A love of shiny items
  • Territorial behavior
  • A tribal culture

This section doesn’t affect mechanics, but it adds depth.


Step 6: Save, Publish, and Test

Once your monster feels complete, click:

Save Changes → [Share Options]

You can:

  • Keep it private
  • Share with your campaign
  • Publish publicly

Testing Matters

Run a quick encounter at your table. See how the monster feels.
You may need to adjust:

  • HP
  • Damage output
  • Actions
  • Traits
  • CR level

Homebrew is iterative by nature.


Step 7: Troubleshooting Your Homebrew

Common D&D Beyond quirks:

  • CR may not calculate until all actions and traits are completed
  • Saving Throws must be entered manually
  • Damage fields sometimes require refreshing
  • Publicly shared monsters need fully original text

If something breaks, try:

  • Removing and re-adding the problematic field
  • Saving, refreshing, and reopening the editor
  • Checking for required fields you may have skipped

“Homebrewing isn’t about perfection — it’s about bringing your world to life.”


Final Thoughts: You Can Make Anything

Homebrewing monsters on D&D Beyond is a fun, creative way to personalize your campaign. Whether you’re designing a Piglin, a cosmic horror, or a humble forest critter, the tools are flexible enough to support almost any idea.

Start small. Test often. Revise freely.

Your world is yours to shape — one monster at a time.
