1. Falconry - the idea is that you could tame a hawk,falcon as your pet to help you in battle against other animals foxes etc. ,but it could hunt rats on its on
to tame you would require to catch a rat and make a trap out of it or smth dont realy have fully figured out how it would work (the taming process)
2. Blackpowder - would be made from 3 ingredients sulfur (could be found in caves or mining shafts as mineral ) charcoal ( would be made by burning wood or branches) and potassium nitrate ( could be made mixing manure in a tub with ashes and waiting for few hours )
3. Cannon - would be made from iron but not like the modern one but the old ones with rings on it to keep it stable and it would use blackpowder and metal or stone cannon balls , but the cannon would be susceptible to explode (if used too much or just by chance) and would kill anione in 10-20 step radius
4.Village/Town house a different kind of house with some carvings or heads on it . That could only be placed by village chieftain but anyone from the village could help build it.
5. Throne - some pretty big chair with carvings for the rulers to sit
6. Walls - when you go into a house
7. Paintings-Wall rug - self explanatory, that can be put on a house walls
8. Tar- would be naturaly occuring tar pits could be used on fire arows or to set wooden thing on fire
9. Fire - burning buildings and walls down
10. Fire arrows - arrows dipped in tar
11.Wall that you can walk on and make the rain of arrows on anyone who attacks your village or just animals

12.Wall shields- shields as wall decorations
13.Seasons - I know this idea has been said many times but i like it too
