Gnome Ranger Build Guide

Levels 1-4

Start with Deft Explorer (Canny) and grab Expertise in Stealth to capitalize on your high Dexterity. At level 2, take the Archery Fighting Style; that +2 bonus to attack rolls is mathematically mandatory to offset the Sharpshooter penalty we will take later. At level 3, select the Gloom Stalker archetype. Dread Ambusher gives you a critical extra attack on turn one, and Umbral Sight turns your Gnome Darkvision from 60 to 90 feet while making you invisible in darkness. For your level 4 Ability Score Improvement, take the Crossbow Expert feat. This lets you fire a Hand Crossbow as a bonus action, doubling your damage output in Tier 1.

Levels 5-10

Level 5 brings Extra Attack and 2nd-level spells. With Crossbow Expert, you are now firing three Hand Crossbow bolts per turn. At level 7, Iron Mind gives you Wisdom saving throw proficiency. Combined with Gnomish Cunning, you roll Wisdom saves against magic with both proficiency and advantage—a mathematical fortress. At level 8, take the Sharpshooter feat. Your Archery fighting style mitigates the -5 penalty, allowing you to add +10 damage to all three of your attacks, skyrocketing your DPR.

Levels 11-16

At level 11, Stalker's Flurry guarantees that if you miss one of your Sharpshooter attacks, you get to immediately make another weapon attack. This dramatically raises your reliable DPR floor. Use your level 12 ASI to bump Dexterity to 17 (assuming a 15 start). Level 14 grants Nature's Veil, letting you spend a spell slot to become invisible as a bonus action—an incredible defensive tool when Umbral Sight's darkness isn't available. At level 16, take the Squat Nimbleness half-feat. This rounds your Dexterity to 18, gives you proficiency in Acrobatics, and crucially bumps your Gnome walking speed from 25 to 30 feet.

Levels 17-20

Level 17 unlocks 5th-level spells, granting you access to Steel Wind Strike or Swift Quiver. Feral Senses at level 18 ensures you never suffer disadvantage when attacking invisible enemies. For your final ASI at level 19, take Resilient (Constitution). This rounds your odd Constitution score to 14, granting you proficiency in Constitution saving throws. This ensures your concentration on critical spells like Pass Without Trace or Conjure Animals rarely breaks under enemy fire.

Cantrips

Rangers do not receive cantrips natively unless you take the Druidic Warrior fighting style. Since we absolutely need the Archery fighting style to make Sharpshooter viable, we skip cantrips entirely.

Level 1-2 Spells

Take Absorb Elements immediately; while Gnomish Cunning gives you advantage on saves against magical fireballs, Absorb Elements halves the damage when you inevitably take a hit. Hunter's Mark is a trap for this build because it competes with your Crossbow Expert bonus action; skip it. Instead, rely on Pass Without Trace at level 5 to give your entire party +10 to Stealth, guaranteeing surprise rounds for your Dread Ambusher feature.

Level 3-5 Spells

At 3rd-level spells, grab Conjure Animals. Because you are a Small Gnome, you can legally summon Medium beasts (like Pteranodons or Giant Frogs) and use them as highly mobile, expendable flying or swimming mounts. Guardian of Nature is your go-to 4th-level spell, granting advantage on all Dexterity-based attacks to guarantee your Sharpshooter shots land. For 5th-level spells, Swift Quiver is decent, but since your bonus action is already occupied by Crossbow Expert, Steel Wind Strike provides a better massive AoE burst option.

Crossbow Expert

Take this immediately at level 4. Because your Small size imposes disadvantage on Heavy Crossbows and Longbows, the Hand Crossbow is your only optimal weapon. This feat removes the loading property and gives you a vital bonus action attack every single turn, completely defining your combat loop.

Sharpshooter

Grab this at level 8. Trading a -5 penalty to hit for +10 damage is the cornerstone of 5e ranged optimization. Because you have the Archery fighting style granting +2 to hit, the penalty is effectively only -3. Firing three shots a turn with a +10 damage modifier is how you keep up with the Fighter and Barbarian.

Squat Nimbleness

A phenomenal half-feat specifically for Small races like Gnomes. Take this at level 16 to round out an odd Dexterity score. It permanently fixes your sluggish 25-foot walking speed by increasing it to 30 feet, and gives you advantage on escaping grapples—essential when a monster gets into melee with your tiny frame.

Resilient (Constitution)

Take this at level 19 to round out your Constitution to 14. Rangers cast powerful concentration spells like Pass Without Trace and Conjure Animals. Proficiency in Constitution saves ensures you won't drop these spells when an enemy manages to hit your high Armor Class.

Tier 1 (Levels 1-4)

Start with Studded Leather Armor and the best Hand Crossbow you can afford. Keep a Rapier and a Shield on hand for moments when you are forced into melee before you acquire Crossbow Expert, though you should strive to stay at range.

Tier 2 (Levels 5-10)

Seek out a +1 Hand Crossbow to offset your Sharpshooter penalty. A Cloak of Elvenkind is best-in-slot here; when combined with your Expertise in Stealth and Umbral Sight, enemies will mathematically never detect you in dim light or darkness.

Tier 3 (Levels 11-16)

Upgrade to a +2 Hand Crossbow. Look for Serpent's Scale Armor (from Candlekeep Mysteries) which allows you to apply your full Dexterity modifier to scale mail without imposing disadvantage on Stealth. Boots of Speed are also critical here to fix your 25-foot Gnome movement speed, allowing you to kite enemies effectively.

Tier 4 (Levels 17-20)

Do not be tempted by legendary weapons like the Oathbow—it is a Longbow, and your Small size means you will roll all attacks with it at disadvantage. Stick to a +3 Hand Crossbow. A Blood Fury Tattoo is your ultimate goal, adding 4d6 necrotic damage to your rapid-fire Crossbow Expert attacks and healing you simultaneously.

As a Gloom Stalker Gnome Ranger, your role is a pure Striker and infiltrator. You operate best in total darkness, meaning you need party members who don't rely on holding bright torches that ruin your Umbral Sight invisibility.

A Twilight Domain Cleric is your absolute best friend. Their Twilight Sanctuary creates dim light, which triggers your Umbral Sight to make you invisible, while granting you constant temporary hit points. Furthermore, their Vigilant Blessing gives you advantage on Initiative, almost guaranteeing you go first to unleash your Dread Ambusher attacks.

You also desperately need a dedicated frontline defender like a Cavalier Fighter or Oath of the Crown Paladin. Because your Gnome walking speed is only 25 feet early on, you cannot kite enemies as effectively as a Wood Elf. A tank that can lock down enemy movement ensures you can stand still and unload your Hand Crossbow without taking opportunity attacks.

Fighter 2 Dip

Taking two levels of Fighter after Ranger 5 is a massive DPR upgrade. You gain a second Fighting Style (take Defense for +1 AC) and Action Surge. Because Gloom Stalker's Dread Ambusher triggers on the Attack action during your first turn, Action Surging gives you another Attack action, which triggers Dread Ambusher a second time. This results in six Hand Crossbow attacks on round one.

Rogue (Assassin) 3 Dip

Taking three levels of Assassin Rogue synergizes flawlessly with Gloom Stalker. Expertise in Stealth and Pass Without Trace almost guarantees surprise. The Assassinate feature means any hit against a surprised creature is an automatic critical hit. Firing 6 attacks on turn one (with Action Surge) that all automatically crit will instantly delete any boss in the game.

• Using a Longbow or Heavy Crossbow: As a Small creature, the Heavy weapon property imposes permanent disadvantage on your attack rolls. Do not equip these under any circumstances; rely strictly on the Hand Crossbow or a Shortbow.
• Casting Hunter's Mark: Hunter's Mark costs a bonus action to cast and move. If you have Crossbow Expert, casting this spell costs you a Hand Crossbow attack. The math dictates that taking the attack with Sharpshooter yields higher DPR than the 1d6 from the spell.
• Forgetting Gnomish Cunning limits: Gnomish Cunning grants advantage on INT/WIS/CHA saves strictly against magic. It does not help you against a Dragon's Frightful Presence or a non-magical monster ability. Read the monster abilities carefully.
• Standing in the Paladin's Light: Gloom Stalker's Umbral Sight only makes you invisible in darkness. If your party's Cleric or Paladin casts Light on their shield and stands next to you, you lose your invisibility. Coordinate positioning.
