## Introduction

Derro (Labyrinth Worldbook) are underworld survivors shaped by darkness, isolation, and contact with things beyond the stars. Mechanically, they are a defensive Small lineage with exceptional vision and one of the best anti-horror packages in the expanded roster.

Derro are strongest in campaigns where psychic damage, fear, charm, dread, void taint, and deep exploration matter. In a bright wilderness campaign, they lose some shine. In a Labyrinth campaign full of dead worlds, Void cults, and buried passages, they feel purpose-built.

## Lineage Traits

### Rating Key

- <span style={{ color: '#ef4444' }}>●</span> **Red** - Bad.
- <span style={{ color: '#f97316' }}>●</span> **Orange** - Situational.
- <span style={{ color: '#22c55e' }}>●</span> **Green** - Good.
- <span style={{ color: '#3b82f6' }}>●</span> **Blue** - Fantastic.

Options from Labyrinth Worldbook are marked with `(Labyrinth Worldbook)`.

### Small Size <span style={{ color: '#22c55e' }}>●</span>

Small size helps with stealth, positioning, and tight environments. It also locks you out of Heavy weapon builds, so avoid Derro if your plan is a greatsword or maul frontliner.

### Superior Darkvision <span style={{ color: '#3b82f6' }}>●</span>

Darkvision to 120 feet is excellent in underground and night-heavy adventures. The drawback is sunlight sensitivity for sight-based Perception checks, which matters in open daytime travel.

### Dread Within <span style={{ color: '#22c55e' }}>●</span>

Advantage on saves against being charmed or frightened is broadly useful. It is especially good for scouts, casters, and anyone who cannot afford to lose actions to control effects.

### Psychic Barrier <span style={{ color: '#3b82f6' }}>●</span>

Psychic resistance plus advantage against dread and void taint effects is the reason to pick Derro. This is campaign-dependent, but in the right campaign it is a premium defensive identity.

## Best Classes for Derro

### Rogue <span style={{ color: '#3b82f6' }}>●</span>

Small size, huge darkvision, and mental defenses make Derro excellent scouts and infiltrators.

### Warlock <span style={{ color: '#22c55e' }}>●</span>

Warlock fits the eldritch theme and appreciates the defensive package. Derro can stand closer to psychic and horror threats than most casters.

### Wizard <span style={{ color: '#22c55e' }}>●</span>

Superior Darkvision is useful for dungeon play, and Psychic Barrier helps keep the Wizard online against mind-affecting enemies.

### Ranger <span style={{ color: '#22c55e' }}>●</span>

Derro Ranger works best in underground, ruins, and survival campaigns where long-range darkvision creates real tactical value.

### Fighter <span style={{ color: '#f97316' }}>●</span>

Dexterity Fighter works fine. Strength Heavy weapon Fighter does not.

## Heritage Pairings

**[Fallen (Labyrinth Worldbook)](/articles/tales-of-the-valiant/heritage-guide#fallen-labyrinth-worldbook)** <span style={{ color: '#3b82f6' }}>●</span>
The cleanest grim-survivor pairing and one of the book's recommended Derro heritages.

**[Void-Touched (Labyrinth Worldbook)](/articles/tales-of-the-valiant/heritage-guide#void-touched-labyrinth-worldbook)** <span style={{ color: '#3b82f6' }}>●</span>
The most on-theme option. Pick this when the character should be unmistakably shaped by Void contact.

**[Salvager](/articles/tales-of-the-valiant/heritage-guide#salvager)** <span style={{ color: '#22c55e' }}>●</span>
Good for underworld scavengers, ruined-world survivors, and practical explorers.

**[Cloud](/articles/tales-of-the-valiant/heritage-guide#cloud)** <span style={{ color: '#22c55e' }}>●</span>
Adds arcane utility to a lineage already tied to strange knowledge and eldritch pressure.

### Player's Guide 2 Heritage Options

**[Conflicted (Player's Guide 2)](/articles/tales-of-the-valiant/heritage-guide#conflicted-players-guide-2)** reinforces derro paranoia, rival enclaves, and survival amid hostile factions.

**[Covenant (Player's Guide 2)](/articles/tales-of-the-valiant/heritage-guide#covenant-players-guide-2)** works for cult obligations, strange vows, and underworld pacts.

**[Hivebound (Player's Guide 2)](/articles/tales-of-the-valiant/heritage-guide#hivebound-players-guide-2)** supports tight underground communities and group survival.

## Hot Takes

> **Hot Take:** Derro (Labyrinth Worldbook) is not a generalist lineage. It is a campaign call. In a normal city-and-wilderness game, it is merely fine. In a Void, horror, or underground campaign, it is one of the best defensive picks on the board.

> **Hot Take:** Superior Darkvision is easy to underrate because many characters have darkvision. Doubling the range changes dungeon scouting, ambush detection, and ranged engagement distances.

## Final Notes

Derro (Labyrinth Worldbook) is a specialist defensive lineage for dark, strange campaigns. Build one when the table is actually using the Labyrinth's horror and Void material, and handle the lore with care.
