Pufferfish's Unofficial Additions
by Cadentem
Pufferfish's Unofficial Additions gives server-side experience sources and rewards, including experience for casting Iron's Spells 'n Spellbooks spells and bonuses tied to crops, fishing and loot.
What it does
The mod adds extra ways to earn experience. One source awards experience each time a spell is cast, and for continuous spells it can trigger on every spell tick, so the amount depends on the spell's expected ticks parameter. Support for Iron's Spells 'n Spellbooks is included, and that mod is optional.
Other hooks react to harvesting, fishing and loot tables. Harvest rewards depend on the player, the block being harvested and the tool in use, with seed and crop drops scaled by the forge:seeds and forge:crops values. Fishing and loot results can also be modified before they reach the player.
Pufferfish's Skills is required, and the mod runs on the server alone, so players join without installing it. It is open source under the MIT License and published for Forge and NeoForge, with game versions 1.19.2 – 1.21.1. The latest Forge file is 2.2.4 for 1.20.1 and the latest NeoForge file is 2.2.8 for 1.21.1, both dated 2025-12-28.
