A gel-like substance naturally produced by Insectoids. It comes in a variety of colors with varying properties.
“This red one has a powerful stench, and the drones identify each other by smell. In theory, we could use the ichor to mask our scent. As far as the drones are concerned, we’d be invisible, but red ichor burns my skin.“ - Nayo - The Hive (GS-ADV3)
Blue ichor is traditionally used as a healing salve by direct application;
“The blue ichor has medicinal properties. They use it to repair injured drones and even to extend their lifespans. Normally the queen provides it to only her most loyal subjects.” - Unnamed Dwarf miner - The Hive (GS-ADV3)
Slightly sweet-smelling, golden ichor has restorative properties, renewing stamina and energy upon consumption;
The golden ichor tastes like honey. Though it sticks to your hand and is difficult to chew, it fills you with a burst of strength and vigor. - The Hive (GS-ADV3)
Golden ichor appears thicker than other types of ichor. It is not possible to mix with the others.
In contrast, red ichor is caustic, melting matter and acting as an explosive agent when ignited;
“Red ichor is slow and corrosive, but, when exposed to heat, it creates a powerful explosive.” - Eregrun - The Hive (GS-ADV3)
Ichors can be combined together, changing their color and providing the benefits of both its parts;
You consider the properties of the blue and red ichor. If combined, the odor of the red should mask your scent, and the healing powers of the blue should counteract the red’s corrosiveness. You mix the two together, creating a purple sludge.
To test your concoction, you pour a single drop onto a rock. When it doesn’t dissolve, you pour another onto your hand. It is not acidic enough to burn your skin, but the stench remains overwhelming. - The Hive (GS-ADV3)
Other combinations of different ichors do not yield exciting results;
The Insectoid colony stow the various ichors they produce into holes that permeate the walls of their Hive for safekeeping;
Hundreds of drones collect a blue ichor and stuff it into tiny holes burrowed into the mountain rock. - The Hive (GS-ADV3)
To those with a magically-refined palate, red ichor boasts savory notes;
It has a wonderfully rich and smoky flavor with plenty of spice. - The Hive (GS-ADV3)
The vapors of blue ichor (to those not allergic) are reported to smell fresh and sharp;
Nayo breathes in deep and then smiles. “That smells good,” she admits. “Like peppermint.” - The Hive (GS-ADV3)
Ichor can be forged to create pieces of armor. - Explorer's Guide (GS-Guide-ADV3-12 & ADV3-15 & AVDV3-22)
