Proficient vs Non-Proficient Checks

In Dungeons & Dragons 5th Edition, few moments are as satisfying as watching a character excel at what they were built to do. The rogue slips a lock open with practiced ease. The bard talks their way past a suspicious guard. The wizard deciphers an ancient rune no one else understands. These are the moments where character choices pay off—where expertise shines.

But at many tables, those moments are quietly undermined.

You’ve probably seen it happen. The rogue, with a sky-high Dexterity and proficiency in thieves’ tools, rolls poorly and fails to pick a lock. Then the barbarian—who has never handled lockpicks in their life—grabs the tools, rolls a lucky 19, and pops the chest open. The table laughs. It’s memorable. But it also raises an uncomfortable question: if anyone can succeed with a lucky roll, what’s the point of specialization?

It’s a common frustration: situations where a highly skilled character (like a rogue) fails an ability check, only for an untrained character (like a barbarian) to succeed with a lucky roll. This undermines character specialization and makes expertise feel irrelevant.

The Problem with “Everyone Rolls”

At its core, the problem isn’t the dice—it’s how Difficulty Classes (DCs) are being applied. Too often, Dungeon Masters assign a single DC for a task and allow every player to attempt it under identical conditions. The result is a kind of statistical inevitability: if enough people roll, someone will succeed.

This “pile-on rolling” erodes the value of proficiency. It turns carefully built characters into interchangeable dice rollers. And it creates a strange incentive where every player carries tools they aren’t trained to use, just to maximize the party’s chances through brute-force probability.

That’s not a failure of the rules—it’s a failure in how they’re being interpreted.

Understanding Ability Checks Properly

Ability checks in D&D are not meant to exist in a vacuum. They are influenced by three critical factors:

Non-Proficiency
A character without training can still attempt many tasks. They rely purely on natural ability—Strength to swim, Dexterity to balance, Intelligence to recall. But they lack refinement, technique, and efficiency.

Proficiency
Training matters. A proficient character adds their proficiency bonus, representing learned skill, experience, and practice. This is the difference between guessing and knowing.

Tools
Some tasks require the right equipment. Lockpicking without thieves’ tools, or crafting without proper instruments, isn’t just harder—it may fundamentally change what’s possible.

These distinctions aren’t cosmetic. They’re meant to shape outcomes.

The Missing Piece: Adjusting Difficulty

According to Jeremy Crawford, Dungeon Masters have full discretion to modify DCs based on circumstances—including whether a character has proficiency or the proper tools. Published adventures often assume that characters attempting tasks are appropriately trained and equipped.

When DMs ignore that assumption and apply the same DC universally, they flatten the system.

Instead, DCs should reflect the reality of the attempt.

Consider the classic locked chest:

• A rogue with proficiency and proper tools might face a moderate DC (around 15).
• A character with tools but no proficiency might face a hard DC (20–25).
• A character without tools—or using improvised ones—might face an even higher DC (25–30).
• A completely untrained character without tools may find the task nearly impossible.

This isn’t about punishing players. It’s about respecting the fiction. Locks are designed to keep people out. Expertise exists for a reason.

Let Experts Be Experts

When DCs are adjusted appropriately, something important happens: specialists regain their spotlight.

The rogue becomes the obvious choice for handling traps and locks. The bard takes the lead in negotiations. The ranger navigates the wilderness with confidence. Other characters can still attempt these tasks—but they do so at a meaningful disadvantage.

This reinforces party roles and encourages cooperation. Instead of everyone rolling, players start asking: Who is best suited for this?

That shift changes the tone of the game.

What About Story-Critical Moments?

There is, of course, an exception worth considering. When success is essential to moving the story forward, rigid adherence to difficulty can stall the game.

In these cases, a DM might:

• Allow a skilled character to succeed automatically or behind the screen
• Reduce the DC to ensure progress
• Provide alternative paths to success

The key is intentionality. These moments should feel like narrative decisions, not mechanical loopholes.

A Better Table Experience

When proficiency and tools are treated as meaningful factors, the game becomes richer:

• Character choices matter more
• Party roles feel distinct and valuable
• Success feels earned, not random
• Failures feel logical, not arbitrary

Most importantly, players feel rewarded for the characters they’ve built.

Because at the end of the day, D&D isn’t just about rolling dice—it’s about telling a story where each hero has a role to play. And when the system supports that, everyone at the table benefits.
