Resource Contraptor.- Not sure what that means though, basically it sound like contraption so I used it, meant to be the Mill building. Nothing special about it, looked like a mine with a cylinder at the side
Wind Spire.- Air unit producing building and ownage device, could transform itself into a unit, some sort of air/thunder/rock elemental.
Gate Keeper Nest/Gate Keeper.- Defensive unit, like the head of a worm, with spikes around.
Essence Sanctuary.- This looked like some sort of proto's pylon, should give a life and mana regeneration bonus.
Units
Slave.- Can mine and chop lumber but will attack or wont respond nor move if its not assigned to a summoner (Not sure if that mechanic would work though, could be very annoying lol), his attacks are slow and have does low damage.
Summoner.-Summons buildings, is fast can attack, has normal damage (its not a weak builder) and can have up to 5 slaves, he doesn't do much more.
Imp.- flying unit, not much to say about it.
