Dragonborn Rogue Build Guide

Levels 1-4

Start with a Rapier, a Shortbow, and leather armor. At level 3, take the Phantom archetype. The Phantom's Wails from the Grave feature adds necrotic splash damage to your single-target Sneak Attack, which pairs beautifully with your Breath Weapon for crowd control. Since your Intelligence is 14, use Whispers of the Dead to grab proficiency in Investigation or thieves' tools whenever you need it. At level 4, take the Piercer feat to bump your Dexterity to 16 and reroll those low 1d8 rapier damage dice.

Levels 5-10

Level 5 is a massive power spike. You gain Uncanny Dodge to halve incoming attack damage, 3d6 Sneak Attack, and your Gem Dragonborn flight. You can now fly above the battlefield, shoot your shortbow, and use Cunning Action to Hide behind rafters. At level 7, Evasion stacks with your innate Draconic Damage Resistance—if you take a Red Dragonborn's fire resistance, a Fireball deals quarter damage on a failed save and zero on a success. At level 8, use your Ability Score Improvement to increase Dexterity to 18.

Levels 11-16

At level 11, Reliable Talent comes online. Combined with your 14 Intelligence and Expertise, you will never fail an Investigation check to find hidden doors again. Level 12 brings another ASI; cap your Dexterity at 20. At level 13, the Phantom's Ghost Walk feature lets you hover and move through objects. Combine this with your Gem Flight to literally phase through dungeon ceilings. At level 16, take the Resilient (Wisdom) feat to bump your 10 Wisdom to 11 and gain proficiency in those crucial saving throws against paralysis and charm effects.

Levels 17-20

At level 17, Death's Knell upgrades your Wails from the Grave, allowing you to deal Sneak Attack damage to both your primary target and secondary targets reliably. Your DPR at this stage hits 41.8, and you can harvest soul trinkets for free. At level 19, take the Tough feat. With a base Constitution of 13, your HP is relatively low for a striker (105 at level 17); Tough provides a badly needed buffer of 40 extra hit points for the final tier of play.

Piercer

Take this at level 4. It provides a +1 to Dexterity (rounding your 15 up to 16) and lets you reroll one piercing damage die per turn. This mathematically increases your baseline Rapier or Shortbow damage and makes your critical hits hit significantly harder.

Resilient (Wisdom)

With a 10 Wisdom, you are a massive liability against mid-to-high-tier spellcasters. Taking Resilient (Wisdom) at level 16 gives you proficiency in Wisdom saving throws, protecting you from spells like Hold Person that would otherwise paralyze you and rip away your Uncanny Dodge.

Tough

Take this at level 19. Because you need to get within 15 feet to use your Breath Weapon optimally, you will take hits. Your 13 Constitution leaves you fragile; Tough acts as a retroactive Constitution boost, adding 2 HP per level and keeping you alive in melee.

Alert

If you prefer an aggressive playstyle, swap Tough for Alert. Gaining +5 to Initiative means you can consistently act first, allowing you to fly into position and drop an AoE Breath Weapon on tightly clustered enemies before they take their first turn to scatter.

Tier 1 (Levels 1-4)

Acquire Studded Leather Armor as soon as possible to maximize your AC with your Dexterity modifier. Your immediate priority must be purchasing Goggles of Night; without Darkvision, your Dragonborn cannot effectively scout dungeons without holding a lit torch, which completely ruins your Cunning Action (Hide) attempts.

Tier 2 (Levels 5-10)

Seek out a Cloak of Elvenkind. Even with Goggles of Night, you want advantage on Stealth checks to offset any situational lighting disadvantages. Additionally, look for a Weapon of Warning (Rapier or Shortbow) to prevent the party from being surprised, ensuring you always get your Sneak Attack off in the first round.

Tier 3 (Levels 11-16)

Hunt down a Dragon Wing Bow from Fizban's Treasury of Dragons. It perfectly fits the Dragonborn theme, doesn't require ammunition, and adds an extra 1d6 elemental damage of your draconic ancestry type to every single shot, pushing your DPR well past the 30.25 mark expected at level 11.

Tier 4 (Levels 17-20)

Aim for a Manual of Quickness of Action to break the Dexterity cap, pushing your DEX to 22. Alternatively, a Blood Fury Tattoo is spectacular for a Phantom Rogue, adding 4d6 necrotic damage to your attacks and healing you—massively increasing your survivability in the endgame.

As a Striker, your primary job is to eliminate high-value targets while using your Breath Weapon to clear out low-level minions. Because you rely on Sneak Attack to deal your 41.8 DPR at level 17, you desperately need a dedicated frontline tank who can engage enemies, allowing you to trigger Sneak Attack via the proximity rule.

A Bear Totem Barbarian or a Cavalier Fighter are your best friends. They can lock down enemies in melee, giving you a static target to hit with your Rapier or Shortbow. The Cavalier's Warding Maneuver also provides a great defensive layer if your Uncanny Dodge isn't enough.

Additionally, because of your lack of Darkvision, a Twilight Domain Cleric is the ultimate support pairing. They can use their Eyes of Night feature to share their 300-foot Darkvision with you, completely negating the biggest weakness of the Dragonborn race for stealth operations.

Fighter 2 Dip

Taking two levels of Fighter grants you the Archery Fighting Style (a +2 to hit with your shortbow) and Action Surge. Action Surge allows for a notorious Rogue trick: use your Action to Attack (applying Sneak Attack), then Action Surge to Ready an action to attack on the next creature's turn, allowing you to apply Sneak Attack twice in one round.

Ranger 3 Dip (Gloom Stalker)

Three levels of Gloom Stalker Ranger instantly fixes your lack of Darkvision by granting Umbral Sight. It also makes you invisible to creatures relying on Darkvision to see you. The Dread Ambusher feature pairs perfectly with your Sneak Attack and Breath Weapon, giving you incredible first-round burst damage.

• Replacing Sneak Attack with Breath Weapon on single targets: Your Breath Weapon is for swarms. If there is only one enemy, 3d6 to 9d6 Sneak Attack damage will always out-scale your racial breath damage.
• Forgetting you don't have Darkvision: Attempting to scout ahead in a pitch-black cavern without Goggles of Night or a Twilight Cleric buff means you automatically fail sight-based Perception checks and attack with disadvantage, negating Sneak Attack.
• Wasting Gem Flight in cramped spaces: Activating your 1-minute flight in a dungeon with 10-foot ceilings makes you a hovering target with no cover. Save it for open arenas where you can fly out of melee reach.
• Using Uncanny Dodge against saving throw spells: Uncanny Dodge only halves damage from an attack that hits you. You cannot use it to halve damage from a Fireball—that is what your Evasion and Draconic Resistance are for.
