How about a mode where you need to defend a castle?

The main goal is to defend the castle's emerald storage room. The castle consists of walls, cities and the central building. The goal of the pillagers is to steal all the emeralds from the storages. The emerald storage rooms are located in different places in the city: trading platform, the city's storage room and the central building, where the most amount of emeralds will be kept in. At first they'll need to break the gate to be able to get in the city and while they're breaking the gates, you'll be able to rain down your arrows upon them. After they broke in, the pillagers will start to walk while being group or singly rob the villagers, your mission is to secure and lead the villagers to the central building. The game will be counted as a lose if you die 3 times or pillagers have robbed the entire city

- After the mission you'll be able to buy things with a discount(buff "hero of the village") from villagers. Also you'll be able to take some free items from the villager with presents

- There will be 3 difficulties: normal, hard, nightmare. Depending of the difficulty, in the battle there'll spawn new mobs, i.g iceologer, royal guard, redstone golem and e.t.c. If you win in nightmare difficulty, there'll be a small chance to get an item called "the peacemaker's weapon". It will be like other unique items but also they'll increase the emerald drop chance from mobs

- While you're trying to secure the villagers, for rescuing them they may give you a reward as food or an item
