Derro (4e Creature)
Derro were created by Diirinka in ages past. Actions of their ancestors caused their lands to lie beneath the surface in the Underdark today. Derro resemble small dwarves with pale white to blue skin, usually with shades of gray. Derro are naturally deviant because of their unusual heritage and their creator.
The only unifying trait of the derro is cruelty– every individual, even the children, takes great pleasure in inflicting pain upon others. Other races get the impression that they particularly enjoy breaking the spirit of captured enemies. The chaotic society they form precludes any orderly hierarchy, leading to one that is sparsely populated. Many times a ruler holds power solely because he has enough slaves to enforce his rule. It is rare that a single individual holds any position in society for more than a few months; assassination usually ends their term prematurely. Their deviancy has led to a social law that dictates that only the victim of an attack can press charges against the assailant, so assassinations are commonplace. Derro are worshipers of Diirinka.
Derro Vocalist
Derro vocalists use scream of madness to great effect. Many times it can be found serving under a derro madguard. Arguably more deviant than most of its kin, a vocalist shrieks and howls nearly constantly.

Derro Vocalist Tactics
A vocalist draws opponents in close with its hand crossbow. Once it has its opponents nearby it unleashes its scream of madness. After screaming it draws its short sword and hacks away.
Derro Madguard
Derro madguards serve as heads of command for small groups of derro. It often leads scouting parties and reconnaissance groups that wander the tunnels farthest from derro cities. The command a madguard offers appeals to many derro who disregard themselves and desire to expedite combat.

Derro Madguard Tactics
A madguard will eagerly fight but prefers to bring other derro, particularly derro vocalists, into the fray so that it can maximize the benefit of its fortification of madness aura. If multiple madguards are working together, they use scream of madness to try to force targets into attacking them. They engage the opponents, allowing the remaining troops to move around and flank the enemy.
Derro Mindscar
Derro mindscars are apprentice magic users whose mental capabilities are flighty. A mindscar's powers often leave victims damaged for extended periods of time, although few actually survive its vicious attacks. It studies under a derro savant and wears a brown robe to signify its status as an apprentice. Though a derro mindscar is only a novice, it considers itself above most other derro; at times small groups of mindscars slay savant masters.

Derro Mindscar Tactics
A derro mindscar's mental powers are unstable and erratic and it knows it. If a mindscar deems an opponent dangerous it will use phantasmal assailants to overpower an opponent's mind and then imitate the opponent for as often and long as possible. If it deems an opponent docile it may try to enslave it. When led by a derro savant it will usually ease the assault as foes weaken so that its more skilled leader can do as he pleases to the victims or otherwise subdue them for later use.
Derro Venomblade
Venomblades focus efforts on mastering the arts of stealth and assassination, rather than developing mental talents. Skilled in the use of many poisons and able to strike before the opponent knows that danger is present, a venomblade can quickly take out small groups of enemies. It is also notorious for infiltrating deep into the heart of hostile cities.

Derro Venomblade Tactics
A venomblade prefers to ambush targets from hiding and will usually refrain from attacking until it can do so with favorable conditions. Its efforts are focused on the most obviously dangerous targets first, especially if it can discern a clear leader amongst the enemy. In groups venomblades quickly flank enemies to make the best use of their assassinate ability or they use scream of madness to temporarily stall combat so they can retreat to more advantageous positions.
Derro Savant, Variant
Derro savants are spellcasters who initially gained power through the chaotic forces of savants' own minds. The powers of a savant's mind are honed to heightened levels through structured discipline and study. Lesser apprentices called mindscars often accompany savants, but they are otherwise rarely found amongst other derro. A derro savant dresses in a dull grey robe made of silk, a rare commodity in the Underdark, to distinguish its superiority over other derro.

Derro Savant Tactics
A derro savant uses illusory wall to set up ambush spots and determine the battlefield. It then hits as many foes as possible with illusory ambush. A savant typically reserves scream of madness for particularly troublesome opponents. Use of scream of madness by the derro savant will cause its victim to turn against its own forces. If the savant gets overwhelmed it is not uncommon for nearby allies to die for him.
Derro Lunatic Priest
Derro lunatic priests are fanatical worshipers of Diirinka and are the highest-ranking of the derro. A lunatic priest dresses itself in a ceremonial white robe emblazoned with hundreds of gaping smiling mouths, the holy symbol of its deity. A lunatic priest is the voice of Diirinka.

Derro Lunatic Priest Tactics
A lunatic priest is more concerned with spreading the mad word of Diirinka than its own life. Thus it fights with reckless abandonment, attempting to strike as many opponents as possible with perfect deviancy so that they will be afflicted even if the priest should die. If it can, it will use Diirinka's hideous laughter on foes to weaken their resolve before using other abilities. A derro lunatic priest will normally explain its understanding of the Far Realm they have mastered in Diirinka's name by summoning a few creatures from its fabric as combat gets hairy.
Derro Lore
A character knows the following information with a successful Nature check.
DC 15: Derro are warped crossbreeds of human and dwarf that live beneath the surface of the earth, deep within the Underdark. They are wholly evil and take great pleasure in enslaving and torturing others. Derro have little society.
DC 20: Most derro prefer to take prisoners and slaves instead of killing their opponents. Slaves usually wind up dying in derro cities. Derro are worshipers of Diirinka, the patron deity of betrayal, cruelty, insanity, knowledge, madness, and treachery.
Encounter Groups
Derro are rarely encountered alone. Since derro are regarded as enemies by most other races, save for a few they may make agreements with, they are usually only accompanied by a handful of their kin. Often, the only races which accompany them are enslaved.
