Oxylla - Silver scaled lizard-humanoids that dissolve metals

For a while I wasn't using many common creatures, I farted around to create weird combos.  These replaced the rust monster in my dungeons. Weird, mysterious insect-lizardmen that kind of worshiped and used silver for all sorts of arcane/cultish designs. This was one of those that I really liked and kept using, even after switching back to the core book of creatures.

Dissolving Touch: Excluding silver, their touch dissolves up to 200 pounds of metals instantly; mundane items do not get a saving throw. Magical items can save vs Fort DC 18 to avoid this affect. Silver can be dissolved, but they must touch the item for one minute. However, the silvery liquid when applied to wounds acts as a healing salve. For every ten coins (10 onces) of silver, an Oxylla can heal 1d10 points of damage. If kept in a secure container, others can use the salve for up to a week later before it fully re-solidifies.

Glue: From their palm orifice they can release a colorless and odorless glue, which takes one round to smear on an object and another round to activate as it dries. This substance bonds any two physical objects for up to one hour. It is incredibly difficult to remove, requiring a Strength Check vs DC 30.

Silver scaled lizard-humanoids that combine the features of lizards, insects and men. These slim humanoids mix silver scales of a dragon, the eyes, antennae and legs of an insect along with a lizard-men’s large strong tail. They have a narrow elongated head. At the end of their long arms, four clawed fingers emerge with a small sticky black circle in the middle of their palm. This orifice is both the equivalent of their nose and an organ to release a glue-like substance upon touch. Oxylla are metal eaters, despised for their ability to absorb and digest metals.

Little is known about the habits or society of these beings. While they sometimes survive by stealing scraps of refuse metal, they often raid traveling merchants or scavenge battle sites to get the needed metals. Metals are food, clothing and elixir; each has a unique taste to an Oxylla, and they can identify the purity or composition of a metal simply by smelling it. Silver is needed in medicinal, religious and reproductive purposes. They speak their own language and dwarven but can speak any if exposed to it or trained.

Combat
Although they survive through raiding, Oxylla use their stealth abilities to take whatever they need without confrontation. While their main tactic is pummeling enemies with their fists, their strongest abilities come from using their long tail to both knock weapons out of opponent’s hands or to trip their enemies.
