The denizens of the slums outside the Grand Arena are crafy tinkerers who can make useful items out of most refuse and trash. So the specialized pieces of monsters and creatures can be used by many crafters to create items of significance. The primary area to find tradesman and crafters for these items isat @Maintenance Bays and at @Slum Row but others interested in these items exist all throughout the slum towns although they will only work in trade and barter.
Within the Grand Arena, however is a different story, with many of these items being contraband and highly controlled. @Meryl "Derringer" Scope will pay you full price, in Flex, for these items if you approach her privately.
@Abomination Core found at the heart of a defeated @Sludge Lake Abomination the abomination core is a solidified mass of toxic chemicals, pulsing and glowing. Scav Shamans can harness the powers of the core to fuel powerful spells. Although crafters in the slums have not found a way to harness the core, they will still trade eagerly to get a chance to experiment with one.
@Scav Raider Ore is a crude metal ore mined in secret Scav tunnels. Usually being carried by @Scav Raider it is a valuable commodity as it is the only source of metal that isn't from the Grand Arena. A base ore it can be utilized by almost any craftsman as they would use iron for.
@Intact Desert Worm Chitin and @Pristine Desert Worm Skull are found on the corpses of slain @Desert Worm. The chitin can be fashioned by armor crafters into durable armors. Some Scav's use this chitin to create small desert dwellings. An intact and pristine skull is a valuable trophy of your mastery over the beasts, but it is of little use to crafters.
@Sand Kraken Beak pried from the slain corpse of a @Sand Kraken this impossibly hard beak can only be manipulated by the most Masterful of crafters. Extremely difficult to work with it makes a valuable trophy. If a smaller weapon, such as a dagger or boomerang, is made with this material it will gain the Indestructible trait. The once Grand Champion @Edward Lox used her famous weapon @Kraken-Club that was made with several of these beaks.
@Vial of Salt Flat Spores living spores harvested from a @Salt Flat Spore Bloom. it is highly prized for its raw psychoactive affects, but some alchemists can concentrate the spores into a potent poison. @Edward Lox is the only one who knows how to refine the spores into the highly addictive @Arena Candy .
@Briggs Ice Giant's Claw an intact hand of a slain @Briggs Ice Giant. Hard and cold it can be used to make elemental weaponry, jewelry to protect against heat and fire, or be used to provide cold temperatures to an area. One of these claws is owned by @Cherize Soutan and used to keep certain medical potions cold and preserved.
@Buzzard-Wasp Wings and @Buzzard Wasp Venom are pieces harvested from slain @Buzzard-Wasp. The wings are highly prized for tailors as they make light iridescent clothing, perfect for nobles night-wear. The venom, difficult to harvest is highly corrosive, highly valued for crafters and alchemists for its acidic nature.
@Pristine Obsidian Butterfly Wing are harvested from slain @Obsidian Butterfly but their hard and sharp nature makes them brittle making them difficult to collect as whole pristine pieces. If they are chipped or broken they are worthless. Weaponsmiths, alchemists, and wizards prize these intact wings for their delicate and specific properties. @Hubbard 'Hub' Soutan has a set of small ultra-sharp scalpels made from these wings he uses for delicate surgeries.
@Mote of FrostHeart can be carved from the 'flesh' of a slain @FrostHeart. These motes can be used by crafters to imbue items with cold resistance or cold damage.
@Wisp Silk can be found after ghosts like @Ancient Ghost or @Apocaghost are slain. When used to weave into clothing it can add subtle illusions to the fabric. Clothing made entirely from this silk could potentially adapt its appearance to any form. Harvesting this much silk would be a near impossible task though.
@Heavy Heart is the immortal drive behind the @Mineral Crusher and must be carved out of the slain for with precision. A single Heavy Heart can heata multi-family slum-town home for several generations. The delicate gem, if harvested by an expert craftsman can be used to create accessories immune to petrification.
@Broken-Ash Wing is the only thing that remains if the @Ash-King is killed. This is a prime example of humanoid flight-ability. It is incomplete. Selling this to @Meryl "Derringer" Scope will result in all future Grand Arena Sentry-bots to be flight-enabled. Bringing this item to @Slum Row and you might find a machinist that will be able to complete the device, wearing the corrected Ash Wing will grant a wearer '20 flight speed. Bringing this item to @Maintenance Bays and you will find someone who will buy the wings for 1-2 random magical items per party member. The result will be a significant shift in the power of the slums over the Grand Arena, as more and more Slum Lords and Slum Gang's gaining the ability of flight.
@Lavos' Core can be shattered from the slain @Lavos Remains. (ENDGAME SPOLIERS: This core is extremely powerful and its hum to pick it up is tempting to all in its presence. Looking into the core while holding it and you will begin to see the collective memories of the planet. The holder of this core will be able to impose their will on a population. Any influences this core creates will persist until the core's destruction. Its destruction will cause ripples through time, returning free-will to those in the past and future who never had the choices. Destroying the core will save the world as the lands will begin to quickly heal as rivers and oceans return to the surface. Ancient forests will regrow and new lands will begin to take sprout.)
@Petrified Lightning is the condensed corpse of a @Thunder Elemental. Enchanters can use this crystal to add lightning resistances or damage to their enchantments. But anyone can throw it as an action; causing this fragile crystal to break cause a strong and spontaneous lightning strike.
@Calypso Flower Petals must be harvested from a live @Calypso Plant, a feat nearly impossible due to the plant's psychic influence and hunger. If able to actually obtain some of these petals they can be processed by expert alchemists to create the @Potion of Confusion or @Poison of Befuddlement . A greater amount of these petals can also be brewed into the fearful @Black Mercy.
@Vine Harvester's Flesh. Who knew that the flesh of a zombie-plant would be good eating? If prepared by an expert cook it can be a delicacy. But any novice leatherworker can tan this hide to make incredibly durable armors, shields, and building materials.
@Harpy Talon must be removed from recently killed @Harpy's. These talons are prized by blacksmiths as they make the sharpest and most durable knives. A knife made from a harpy talon will stay sharp for generations.
