How to Homebrew a Feat on D&D Beyond
Crafting custom character options—one mug of inspiration at a time.
Feats are one of Dungeons & Dragons’ best tools for shaping a character’s identity. A single choice can change how a hero fights, explores, solves problems—or discovers who they’re meant to become. D&D Beyond already provides more than a hundred official feats and tens of thousands of homebrew creations, but sometimes you need something oddly specific… or something the new rules forgot to carry forward.
That’s what happened at my table. When our Voxels & Valor group switched to the 2024 ruleset, our water Genasi paladin lost access to the Call to the Wave feat. It wasn’t updated yet—but for that character, it wasn’t just a mechanical perk. It was flavor, identity, and story. So we rebuilt the feat ourselves. Here’s how you can do the same.
Homebrew isn’t bending the rules—it’s bending the world to fit your story.
Step 1: Create the Feat’s Foundation
On D&D Beyond, open Collections → Homebrew Creations → Create Feat. You can start from an existing feat (the easier route), but this walkthrough uses a from-scratch build.
Tip: If you plan to mirror an existing option, use it as a template first—then edit. It preserves formatting, tags, and common fields, saving time.
Fill in the basic details, then click Create Feat (some fields only appear after the first save):
| Name | Call to the Wave (supplement) |
| Description | You know the Shape Water cantrip. Wisdom is your spellcasting ability for this spell. |
| Snippet | Same as description (appears on the character sheet) |
| Feat Tags | Origin |
| Number of Feat Options | 1 |
Step 2: Add Your Prerequisites
Prerequisites keep your feat from appearing in places it shouldn’t. For our recreation, we mirrored the original restrictions:
| Type | Sub-Type | Value |
|---|---|---|
| Species | Water Genasi | 1 |
| Level | Character Level | 3 |
DM Sidebar: Prereqs are guardrails. Use species, level, or ability minimums to control access and prevent edge-case exploits. If you expect multiclass dipping, sanity-check the timing.
Good prerequisites serve the story first—and the balance a close second.
Step 3: Add the Spell
This feat grants the Shape Water cantrip. To add it: open the Spells section → Add a Spell → select Shape Water → save. No extra configuration needed.
Tip: If your feat grants multiple spells or scaling features, keep the description short and move clarifications to bullet points. Players skim—clarity wins.
Step 4: Save and Celebrate
Click Save Changes. Your new homebrew feat is ready to use. Keep it private for your table, or publish it to gather feedback and help other tables who need the same fix.
The real magic of homebrewing is agency—yours, your players’, and your story’s.
Final Thoughts for Fellow Homebrewers
Homebrew isn’t about breaking balance; it’s about protecting character identity. If a concept relies on an older rule or unported feature, don’t compromise—craft what the story needs, then sanity-check it at the table.
