Madness (Ex)

Derros use their Charisma modifier on Will saves instead of their Wisdom modifier, and are immune to insanity and confusion effects. Only a miracle or wish can remove a derro’s madness. If this occurs, the derro gains 6 points of Wisdom and loses 6 points of Charisma.

Poison Use (Ex)

Derros are not at risk of poisoning themselves when handling poison. They use Medium spider venom to poison their crossbow bolts, and generally carry 10 pre-poisoned bolts at all times.

Medium Spider Venom—injury; save Fort DC 14; frequency 1/round for 4 rounds; effect 1d2 Strength damage; cure 1 save.

Vulnerability to Sunlight (Ex)

A derro takes 1 point of Con damage after every hour it is exposed to sunlight.

Environment any underground
Organization solitary, team (2–4), squad (5–8 plus 1 sorcerer of 3rd–5th level), or band (11–20 plus 30% noncombatants plus 3 sorcerers of 3rd–8th level)
Treasure NPC Gear (leather armor, short sword or aklys, repeating light crossbow with 10 poisoned bolts, other treasure)

A typical derro fights with a short sword or a repeating light crossbow with plenty of poison bolts. Some derros also carry an aklys—a hooked throwing club attached to a 20-foot- long cord. This cord limits the club’s range, but allows the derro to retrieve it as a move-equivalent action after it has been thrown.

Derro leaders are typically sorcerers of at least 3rd level, although they also make excellent rogues. Many derros wield strange and unusual weapons like hooked polearms, eerie whistling aklyses, long hollow spears that can be filled with toxins, or crystalline throwing wedges that shatter on impact to create horrific bleeding wounds.

A derro stands 3 feet tall and weighs 70 pounds.

Derro Encounters

Even though many derros live mere miles below the surface, few surface dwellers know much about the true terror that lurks below. Derros are expert infiltrators who work under the cover of night and skillfully hide their tracks. Underground, they quickly silence any strangers who stumble upon their settlements. Derros target undesirables, slum-dwellers, and people living on a city’s outskirts, for even the shameless derro have learned to avoid reprisal from surface authorities. On these frightful nights, a gang of eight to 12 derros led by a derro bodysnatcher infiltrate a city, quietly subdue unwilling subjects, and drag them below.

Once secured in their territory, derros fasten victims to stone slabs and prepare them for the devious white-eyed torturers who subject their captives to bizarre procedures.

Derros mend and release test subjects who survive this gruesome ordeal, though they often return for future abductions to track their weird experiments’ progress.
