Potion Effects Set
by Etema
Potion Effects Set lets pack makers attach potion effects to items through datapacks, with tiered bonuses for matching pieces.
What it does
Items can grant a potion effect while equipped, when they hit a target, or when the wearer takes damage. A single rule can cover many items by pointing to a tag, and variants of the same base item can be matched through NBT. Custom items can be added to existing loot tables without replacing their entries.
Sets reward players for wearing several matching pieces: a 2-piece set can grant Strength, and a 4-piece tier upgrade can raise it to Strength II. Curios slots are counted, so two matching rings placed in separate slots both contribute. Effects from several active sources stack in a defined way, and sets with different effects, such as Speed, still coexist. The mod is published for Forge 1.20.1 and NeoForge 1.21.1 and uses the same datapack workflow on both branches, so the config format stays familiar. Installation covers the server and each player's game.
Key features
Passive, on-hit and on-hurt effects
Items can apply effects while equipped, when the player lands an attack, or when the player takes damage.
Tag-based item rules
Many items can share one effect setup through tags, and variants of a base item can be matched through NBT data.
Tiered set bonuses
Set bonuses take effect at 2, 3 and 4 matching pieces, with stronger effects at higher tiers.
Curios piece counting
Pieces are counted across Curios slots, so repeated accessories of one kind each add to the set.

What the author says
Datapack-driven item potion effects, set bonuses, Curios support, and loot table injections. Both versions share the same core idea and almost the same datapack workflow, so pack makers can use one system across both branches.
