I believe a pit fall trap would serve the game wonderfully. You would be able to drop people into a room in the underground with arrow towers or better yet mobs you’ve tamed. So you could fall into a pit full of dragons orrr to make this trap interesting you could also set it up to make the person fall all the way into the under world from ground level.
Onto the taming skill, it would use a variety of items within this skill. One of which would be the wip. The wip would only attack from 2 spaces away not like spear that can attack 1 or 2. And you would be able to open or close doors with wip, tame certain mobs, cause ok damage to naked individual, You also would be able to pick up items from a distance with whip.
