Hmm, from what I can remember:
- Made a Cat civ (I remember forgetting to give them intelligence and door opening capabilities). Their main weapons were daggers and blowguns wielded with their mouth. Ever saw a small kitty decapitate a Dorf with a knife between its teeth? Ever wondered how they were able to reload a blowgun after firing?
- Made a new night creature, small, has 4 arms and has syndrome bites. it runs away from adventurers everytime...it had all the aggressive tags and all!
- Made the Merfolk able to shoot out magic ice projectiles.
- Made magical throwing knives. The freezing ones was interesting but fire knives are fun since it boils the targets blood when stuck and also explodes while the target is still alive. Also made some new swords that explode. Also made variations to the magic missile mod to explode in new ways. Also some unique materials...that also explode with fiery death mostly.
No, I'm not Micheal Bay.- Made a Fluffy Wambler King megabeast. It's attacks by glomping you to death. Made another Dragon race with acidic breath to strong...it can take out anyone very slowly and very painfully if they're even hit once. Even in death, it got it's vengeance against the Colossi squad in out breath.
- Latest one I have done is accidentally "fusing" Kobold and Goblin civs that now live in Dark Kobold Fortresses. Gob couples can also give birth to Kobolds and vice versa...
