Sry for the delay, just got to downloading the new techfortress test tree, for the electromagnetics. It sounds like you nailed it - although i might have made the Electromagnetics workshop used for the direct creation og Coilguns as well as electromagnetic coils. But its cool - i like it. Maybe(in the future when the mod is more progress) we can also make Railguns, which will be like Ballistas - bigger and way, way more powerful. Im going - now that V1 of my mod is out - to begin work on a full plan for the tech tree - i only have a bit of a vague outline so far. It will probably feature on the Magnetic/Electric tech tree a load of stuff like Magnetic Forcefields as armor and such. Two other paths I will work on will be Psionics, enhancements for le human(or temporarily dorf) brain, giving that civ abilities like Pyrokinesis, and at top levels, making the people of the fortress immortal. Then there will be Genetic Modification, which allows syndromes to be inflicted in a way not unlike the workshop for the magic we was talkin about, and not unlike the psionic tree either - but its effects will transform the user into mighty beasts and supersoldiers, temporarily or permanently. Also considering Robotics/Cybernetics tree. When I write them up, i will post them here - and if your okay with it, we can start development immediatly. Pikachu17, another creature i wanted to ask you to mage is huge alien behemoth - an herbivore like the wild goats you find in regular DF on mountains, but it will actually be a megabeast. It should - if possible, have somewhat poor sight, but be highly aggressive. Im thinking something that stands 15 feet tall, on two massive, muscled legs with cloven hooves, six beady little eyes, sharp buck teeth in a triangular shape at the front of its mostly molar filled mouth, and giant horns, black as moonless midnight and twice the length of the monsters head. No arms of any sort, but a long, thick tail. And covered in pale green scales.
Thats the first megabeast for the forest world, and for some extra wildlife, i have idea for a predator. It is a four legged egg shaped creature, with a long thin tail that is covered in tiny, venomous barbs. Its venom causes necrosis if it touches flesh, and it runs at at least 1.5X human speeds. Weak on endurance though - a good coilgun shot should kill it, or at least cripple it/cause major blood loss. it should be a white color - like an egg lol - with slick skin and black blood, if possible. Its head and neck should be short, and its mouth should be relatively non-threatening - after all, it rarely uses it to fight, mainly to gorge itself. If possible, give it no nose, and real good eyesight. And it should be a pack animal that travels in groups of at LEAST 3, pref. more.
One last creature - a smaller species of fungoid, it has no vital organs but funnctions as a living creature just the same, made out of soft tissue. It bleeds pale yellow stuff that the egg guy should be immune to, but if ingested by a human causes bloody vomit and lethargy. It runs at slightly slower than human speed, breeds/matures quickly and in litters, its meat is fully edible - unlike its blood - and it can swim well too. It should be like a six legged lizard looking thing, about the size of a cat, but red and bumpy, with no mouth or ears(and no need to eat or drink, it osmosises) and only one eye. No tail either - it has evolved to quickly reproduce in order to survive where other creatures simply became stronger. It should travel in larger packs than the egg beasties. If you could to that it would be really awesome, bro.
