SwagSlayer
Java mod listed for Minecraft 1.21. Download on the author's site.
⬇ Download on SpigotSwagSlayer adds a per-type mob-slayer progression system on top of vanilla combat. Players level up independently across four slayer types (Zombie, Spider, Skeleton, Creeper), each with its own XP, level, and kill count tracked persistently through SwagAPI's shared database.
Features:
- Per-type progression: 4 independent slayer types, each with its own level, XP, and kill count
- Kill tasks: level-scaled kill goals with bonus XP on completion
- Combo streak: rapid kills build a multiplier up to 2.0x XP, decaying after a configurable timeout
- Boss encounters: summon a boss version of a tracked mob from the GUI
- Leaderboards: overall (combined XP) and per-type leaderboard GUIs with player-head icons
- Bestiary and cosmetics: mob bestiary tracking and cosmetic rewards
- Contracts: daily/weekly contract system
- Perks: unlockable perks tied to progression
- Admin tools: /slayadmin reload|setlevel|addxp|reset, all hot-reloadable without a restart
- Optional Discord integration: publishes boss-kill events on SwagAPI's shared event bus for pickup by DiscordUtils
Requirements:
- Paper/Spigot 1.21+
- SwagAPI (hard dependency, provides the shared database service SwagSlayer stores all player data in; SwagSlayer disables itself on startup if SwagAPI isn't loaded)
- DiscordUtils (optional, only for the boss-kill Discord notification)
All player data (levels, XP, kill counts, active tasks, contracts) is persisted through SwagAPI's shared database service, not local files.
