About this Mod

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)

For Modpack/Datapack devs

All the quests are pulled from the json file at "slayerquests:slayerquests" there is also a built in reference/style guide if you unpack the jar. If "mobID" isn't a registered Living Entity, an exception will be thrown. If a loot table isn't found at "lootOverrideDirectory", it will revert to the tier loot table for that quest.

If you change the name of any "tier" objects, make sure to add the loot table "slayerquests:loot_table/tier_loot/tiername" or the mod will throw an exception that there are missing tables.

For devs or artists looking to use the library

Check the documentation here (currently a work in progress): https://github.com/TazgirI/serverside-slayer/wiki

WIP features

Making emeralds named "Slayer Gem" tell you your quests status when right clicked

Adding a tag that applies the default Nitwit quest giving interaction to mobs with it

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

Slayer Quests server crashes on startup – what to do?

Server lagging with Slayer Quests – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Slayer Quests consumes the most tick time.
