Item Coating

A mod that allows applying potion effects to weapons, tools, and armor. Effects trigger on attack, block break, or when taking damage.

Key Features

Apply Coatings: Craft item + potion OR grab potion and right-click item in inventory
Remove Coatings: Grab milk bucket and right-click item to remove all coatings
Three Item Types: Weapons (apply on attack), Tools (apply on block break with Inversion), Armor (apply when taking damage)
Two Effect Types: Time-based (expire by timer) or Hit-based (expire after N hits for instant effects ≤1s)
Extend Effects: Reapply same effect to extend (time-based: full/1/4 duration, hit-based: +1 hit)
Loot Coatings: 8% chance for items in loot chests to spawn with coatings (1% chance for Coating Curse instead)
Better Combat Support: Works with dual wield and offhand attacks

Enchantments

Enchantment	Max Level	Effect
Coating Capacity	III	+1 coating slot per level (base 1, max 4)
Coating Preservation	V	Extends duration: +5s + 20% × 2 × level (time) or +1 + 2 × level hits
Coating Potency	III	+1 effect level per enchantment level
Coating Curse	I	Prevents applying coatings (curse)
Curse of Inversion	I	Inverts effect application (extremely rare treasure)
Curse of Permanence	I	Makes coatings infinite and unremovable (extremely rare treasure)

Item Types

Weapons

Trigger: On attack
Target: Enemy receives effect
With Inversion: Wielder receives effect

Tools

Trigger: On block break (requires Inversion curse)
Target: Player receives effect (only with Inversion)
Without Inversion: No effect (blocks can't receive effects)
Note: Axes are treated as weapons, not tools

Armor

Trigger: When taking damage
Target: Attacker receives effect
With Inversion: Wearer receives effect
Full Set Mode: Optional config to require all 4 pieces with same effect

Curses

Curse of Inversion

Effect: Inverts who receives the coating effect
- Weapons: Effects apply to wielder instead of target
- Tools: Effects apply to player when breaking blocks
- Armor: Effects apply to wearer instead of attacker
Rarity: Extremely rare (1% of normal curse chance)

Curse of Permanence

Effect: Coatings become infinite and cannot be removed
- Coatings never expire (no duration/hit countdown)
- Milk bucket cannot remove coatings
- Can still add new coatings if capacity allows
Rarity: Extremely rare (1% of normal curse chance)

Visual Effects

Particles: Colored particles around coated items (configurable)
Tooltip: Real-time timer/hit counter, effect icons, Shift for descriptions

How It Works

Applying Coatings

Crafting: Item + potion(s) → coated item + empty bottles
Quick Apply: Grab potion → right-click item → instant coating
Works in any inventory: Player, chest, shulker box, etc.

Mechanics

Time-based (>1s potions): Shows "Poison II (1:23)", expires by timer
Hit-based (≤1s potions): Shows "Strength II (3 hits)", expires per use
On Trigger:
- Weapons: Applies effect for 3s (time) or 1s (hit) on attack
- Tools: Applies effect for 1s (time) or 1s (hit) on block break (with Inversion)
- Armor: Applies effect for 3s (time) or 1s (hit) when taking damage
Extension:
- Time-based: Same level = full duration, different level = 1/4 duration
- Hit-based: +1 hit per potion (regardless of level)

Disabled (default): Each armor piece works independently
