The derro are noted for their unusual weapons, specifically weapons designed to subdue or capture rather than kill opponents to haul them off to slavery and experimentation. The canonical examples are the aklys, the fauchard (see below the jump for these).
Their poisoned repeating light crossbow bolts are infamous but Derro poison is probably worth a whole other post…
However, any weapon with the ability to trip, grapple and/or impose pin, tie and entangle effects may be substituted, particularly when combined with feats like Improved Disarm, Improved Grapple, Improved Trip and Net Adept for any derro with combat class levels.
Suggested (Exotic) Derro Slaver Weapons
The following weapons used to disarm, trip, grapple and entangle are all considered Exotic Weapons unless otherwise noted in their descriptions. At the GM’s discretion, any or all of these may be considered martial weapons by standard derro and encountered as armaments of a derro slaver mob.
Further details for each weapon can be found in the d20PFSRD, as well as specific rules for the various special attacks.
Technically a martial weapon (equivalent to a battleaxe) unless used to disarm, this makes a good substitute for the otherwise inspiring standard short sword. It just looks more evil for a start.
Technically only a martial weapon, the bill is somewhat inferior reach weapon when compared to a fauchard and is used to disarm rather than trip. Unlike a fauchard it can also be used to brace against attacks.
A trip attack weapon but with less range than the traditional aklys and no melee attack, it provides a reasonable substitute option.
Also technically only a martial weapon, the gusiarme is a reach weapon similar to the superior fauchard that can be used to both trip and brace.
The derro in the insert picture is probably using this weapon rather than a fauchard. Not to be confused with a glaive or a glaive-guisarme…
An uncommon and unwieldy weapon but one well suited to potentially capturing either Small or Medium opponents with a grapple combat maneouvre after a reach touch attack. Without the Improved Grapple feat, this presumably still provokes an attack of opportunity.
Net / Snag Net
Able to cause an opponent to become entangled (and for a snag net, provoke a trip attack), these weapons are well suited to derro slavers.
Steadfast Grapple / Grappling Hook
Standard Derro Racial Weapons
The following weapons normally require the Exotic Weapon Proficiency feat but are considered martial weapons as per AR12: Derro and can be used without penalty by all derro (including presumably savants).
Ever a signature weapon of the derro since S4 Caverns of Tsojcanth, the fauchard, a somewhat confusingly defined pole-arm, reduced to a clearer description and simple mechanics in the d20PFSRD (originally appearing in Tome of Classic Horrors, page 8):
This polearm is similar to a glaive, being a curved blade affixed to the end of a pole. Unlike a glaive, though, the cutting edge of a fauchard is along the concave side, causing the blade to resemble that of a sickle or scythe.
Benefit: The fauchard is more awkward to utilize than a glaive (and as such is an exotic weapon), but its increased threat range over the glaive and the ability to trip foes make it a dangerous weapon in the hands of a skilled user.
Weapon Feature(s): reach, trip
The aklys is a hooked throwing club with a 20-foot cord attached. Some aklys have holes drilled in them and whistle when thrown, making them ideal for throwing down long, dark tunnels.
