I wanted to homebrew some monsters, so I home-brewed some monsters. I'd love to compare notes, and see the methods other GMs are using to create their own. I'll open with my own example; Limpets (Biomorph) This biological Exurgent was designed to produce swarms of small, efficient creatures with near invulnerability from vacuum. Resembling a breadbox-sized cone snail with a shell of flexible cartilage and a single bone spur for attacking, they are infamous for clinging to derelict ships and abandoned habitats for months or even years after they are supposedly burned clean, hiding in ventilation ducts and other crawlspaces only a few centimeters in diameter. This strain produces three or four Limpets from one adult transhuman body, creating a whole colony just from the inhabitants of one ship. Average Limpet: COG 10 (max 15), COO 15+5 (max 30), INT 10 (max 20), REF 10 (max 20), SAV 10 (max 15), SOM 15+5 (max 20), WIL 10+10 (max 30), No Moxie Durability 30, WT 6, Initiative 30, Lucidity Irrelevant, Speed 1 Movement Rate: Pseudopod 2/8 Skills: Unarmed 20 (spec. stinger), Climbing 50, Infiltration 40, Perception 25. Notes: Armor (6/6), Echolocation, Vacuum Sealing, Chameleon Skin, Stinger Attack (AP -2, 1d10+2), Venom (Application: Injection, Onset Time: 4 Action Turns, Duration: 1 hour, Effect: Roll DURx2 or fall unconscious; cumulative -10 to all actions), Small Target Limpets are rarely out to kill anyone; they will only sting until they get a successful hit in, then scoot away while their victim succumbs to the virus running through their veins. They will only attack in groups of three or more to flank an opponent, though it is not clear whether this is instinct or conscious tactics at work.
