Mercenary

Mercenary is a simple mod that allows you to press a keybind (by default #) whilst near villagers to get a quest for your team

the quest will either be "deliver a package to X" where that location will be a village,
or "you must deal with some rogues at X" where you will have to go to a location (Datapack configurable) that is hostile

both quests require you to place a block at/near the location specified once you have removed all hostile mobs in a
small radius, remaining mobs will be lit up with the glowing effect if they still exist

once you return to a village after completing the quest, you can claim your prize which will be 1-64 emeralds

as of 1.1.0 you can also remove quests that you cannot/don't want to do with right square bracket

you can also press left square bracket to "count" your emeralds for your team, in this case the emeralds in your main hand are removed from you, but it is added to a scoreboard (using the vanilla scoreboard system) - now you can be in competition with other people!

if you don't like keybinds, or have too many, you can also /mercenary quest|count|remove
