Slayer Quests
Java mod listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.
Serverside mod that allows Nitwits to assign OSRS slayer style quests, also works as a library for adding quest functionality to your own mobs
⬇ Download on CurseForgeThe author built this one for Minecraft 1.21.1 on NeoForge. On other versions it may install and then do nothing.
A simply surverside mod that allows Nitwits to assign players simple OSRS Slayer style quests.
Just right click a Nitwit to be offered a quest that you can choose to uptake, right click a Nitwit again to hand in the quest for your loot. Fully configurable including disabling the Nitwit behaviour if you just want library functionality.
There is also a built in levelling system to allow a progression curve.
(sorry if the built in quests and loot tables are a little unbalanced, I went slightly stir crazy making them all at once)

WIP features:
- Making emeralds named "Slayer Gem" tell you your quests status when right clicked
- Detecting mob farms and preventing mob farm kills from counting towards quests
- JEI support so quest tiers come up if you press R on a resource in their loot table
- Allow certain mobs or tag to only be killed if you have an quest for them (for passive mobs with valuable drops)
- Another JSON that dictates quests that are added/removed when different game stages trigger (i.e nether or end opens)
- Aggresive mobs that can only be killed if you have a quest for them will not be aggresive when you don't have a quest
