D&D Homebrew Subclass Creation Step 3: Creating the Subclass
- Apr 24
- 5 min read
Homebrew subclass design in Dungeons & Dragons often feels like stitching together the flair of Attack on Titan, the character growth arcs of Naruto, and the dramatic finales of Breaking Bad—all while staying grounded in the rules that make the game work. This stage of creation is where imagination meets structure, blending creative themes with established mechanics to build something that feels both original and playable. In this final step, the Otaku Bard and the Talisman Monk come to life, combining distinct identities with carefully balanced features that reflect both storytelling depth and gameplay function.
As mentioned earlier, if you're reading this and haven't gone through Step 1: Creating Themes and Step 2: Choosing the Right Class for creating a homebrew subclass, please review those first. This is the final step in the process, and understanding the earlier groundwork is essential.
To recap: we established two core themes—an “otaku” concept and a talisman user. The otaku theme is based on a person deeply immersed in specific aspects of popular culture, often at the expense of social skills. This creates a flexible subclass with multiple directions. In contrast, the talisman concept is more focused, centering on using talismans for various effects.
For these ideas, we selected the Bard class for the Otaku theme and the Monk class for the Talisman user. A socially awkward Bard creates an interesting contrast to the class’s typical charisma focus, while the talisman concept naturally aligns with the Monk, drawing from folklore imagery.
In this blog, we’ll build the subclass features step by step. We’ll examine base class mechanics like “Jack of All Trades” and Ki points, review official subclasses for structure and inspiration, and then present the finished subclasses along with the reasoning behind each design choice.
Understanding the Class:
To better understand how classes work we will focus on the Bard and Monk as an example, it’s important to look at their defining features.
Bard:
Bards are highly versatile, excelling across many skills. Bardic Inspiration allows them to boost allies’ d20 rolls, while Magical Secrets lets them access spells from any class. As full spellcasters, they can cast spells up to 9th level.
Monk:
Monks are highly mobile, capable of moving up to 60 feet. They use Ki points to fuel abilities like additional attacks or stunning enemies, making them adaptable in combat.
Both classes rely on core mechanics that shape their subclasses:
Monk’s Key Abilities:
Ki Points: Fuel abilities like Flurry of Blows, Patient Defense, Stunning Strike, and Step of the Wind.
Martial Arts: Enhances unarmed strikes with scaling damage.Unarmed Movement: Increases movement speed.
Bard’s Key Abilities:
Bardic Inspiration: A scaling die added to d20 rolls.
Magical Secrets: Expands spellcasting options.
Jack of All Trades: Adds half proficiency to non-proficient skills.
Pay close attention to Bardic Inspiration and Ki points, as these are central mechanics frequently used in official subclasses.
Learning From Official Subclasses:
Looking at official subclasses from Wizards of the Coast provides both inspiration and structure.
For example, the Monk’s Way of the Open Hand expands on Ki usage, enhancing Flurry of Blows with added effects like knocking enemies prone or pushing them. Similarly, the Bard’s College of Lore modifies Bardic Inspiration by allowing it to subtract from enemy rolls.
Another key takeaway is feature progression. Bards gain subclass features at levels 3, 6, and 14, while Monks gain theirs at levels 3, 6, 11, and 17. Matching this structure helps maintain balance.
Creating the Subclass:
Level 5 Features or Below:
Subclass features typically begin at level 3. Early features should include both a combat-focused ability and a campaign-focused ability, such as roleplay or utility.
Bard Level 3 Features (Otaku Savant):
You are a true OTAKU, with deep knowledge but social awkwardness. You can substitute your Charisma modifier for Wisdom or Intelligence on related skill checks. However, you suffer a -1 penalty on Charisma-based checks (as if your Charisma were 8). You also gain proficiency with martial weapons and all armor.
Reasoning:
This reflects a knowledgeable but socially awkward character. The flexibility in skill checks supports the theme, while the penalty balances it.
Monk Level 3 Features (Talismans Art, Basic Talismans):
Talismans Art
You are proficient in creating talismans using Calligraphy Tools.
Basic Talismans
You can maintain up to three active talismans. They last 1 hour or until used.
Talisman of Support: Spend 1 Ki point to give an ally within 5 feet a +1d4 bonus to a d20 roll.
Talisman of Pain: Spend 1 Ki point on a hit to force a creature to subtract 1d4 from their next roll.
At level 11, the die increases to 1d6.
Reasoning:
These talismans mirror Bardic Inspiration in a simplified form, offering both buffs and debuffs while fitting the theme. The Talismans Art is great for in game scense that require Calligraphy Tools.
Level 6 - 10 Features:
This range is often considered the “sweet spot” of play, where challenges and mechanics remain balanced and engaging.
Bard Level 6 Feature (Cosplay Convocation):
You can channel fantasy archetypes for 1 hour, twice per rest or by expending Bardic Inspiration.
Fake Rogue: Uses Charisma for Dexterity/Constitution checks, creates magical weapons, and adds bonus damage.
Fake Fighter: Uses Charisma for Strength, gains AC bonuses, and extra attacks.
Fake Wizard: Uses Charisma for mental saves and gains limited spellcasting charges.
Reasoning:
This feature reflects the versatility of cosplay, allowing the bard to temporarily embody different roles.
Monk Level 6 Feature (Divine Talisman Empowerment):
You can place talismans at range and gain access to Cleric spells up to 3rd level, powered by Ki points.
You also learn two Cleric cantrips and can prepare spells based on Wisdom.
Reasoning:
This expands the talisman concept into divine magic while maintaining balance through Ki usage.
Level 11 - 15 Features:
At this stage, enemies become more dangerous, and abilities must scale accordingly. You also will most likely see a dragon (WINK).
Bard Level 14 Feature (Final Episode):
Once per long rest, choose a powerful effect such as ally buffs, personal empowerment, self-sacrifice, or area damage. Each option includes a drawback like exhaustion or unconsciousness.
Reasoning:
This reflects a dramatic “finale” moment, matching the subclass theme while balancing power with consequences.
Monk Level 11 Feature (Divine Talisman Crafting, Homing Talisman):
You gain access to 5th-level Cleric spells and can create three spell-infused talismans per long rest. Talismans can now be used at range.
Reasoning:
This ensures the monk remains competitive with other spellcasting classes while preserving resource balance.
Level 16 - 20 Features:
At this level, characters reach peak power. You are now fighting GODs. You also see new subclass features starting to go away for example the Bard.
Monk Level 17 Feature (Grandmaster’s Talisman):
Spend 5 Ki points to create multiple talismans affecting creatures within 60 feet. These can heal allies or damage enemies, with limits on stacking.
Reasoning:
This provides a large-scale, impactful ability while preventing excessive stacking or imbalance.
Conclusion:
Creating a homebrew subclass requires understanding existing design, maintaining balance, and testing your ideas in play. Studying official subclasses helps guide structure, while playtesting ensures fairness. Whether it’s the Bard’s high-impact abilities or the Monk’s talisman mechanics, each feature should feel meaningful without overshadowing others.
