More ranged weapons. I mean, come on... Maybe magic scrolls you can find in dungeon chests, then you can make spells with them. That would be awesome... A multitool. You would make a pickaxe, but with an axe, a shovel and a pick at the top. Science! Maybe guns? I don't know, I think a musket with a bayonet would be cool, but it might be too advanced. More mobs. Bears, ACTUAL fish, birds, more sea mobs, etc
