Last One Core

A configurable prefix, rarity, and attribute toolkit for Minecraft 1.20.1 Forge.

Last One Core extends Confluence's item-prefix systems with editable prefix pools and compatibility-focused attribute handling. Tune which items can receive prefixes, how prefixes are selected, and how rarity and critical-chance attributes behave—all through configuration.

Features

• Configurable prefix pools: Use exact item IDs, item tags, or namespaces to choose which items use custom pools. Adjust prefix tiers and weights, add your own entries, and use the best roll to select from the highest tier. Built-in categories include melee, ranged, magic, summon, universal, accessory, and armor; custom categories are supported too.
• Armor prefixes: Configure a dedicated armor prefix pool and its attribute modifiers independently from accessory prefixes.
• Prefix initialization on drops: Newly spawned item drops can receive Confluence's normal one-time prefix initialization.
• Rarity remapping: Map Confluence's legacy prefix-quality values or newer tier values onto Minecraft's rarity ranks, from Common through Mythical. Legendary and Mythical text colors are configurable.
• Attribute replacement: Remap attributes on newly generated or rerolled Confluence prefixes. A separate option can replace Confluence Magic Lib's global critical-chance attribute mapping.
• Optional movement compatibility: When both MovesLikeMafuyu and Dungeons Perspective are installed, rolling follows the dungeon-view movement direction.

Requirements

• Minecraft 1.20.1
• Minecraft Forge (47.2.0 or newer)
• Confluence is optional. Prefix, rarity, and Confluence attribute features are inactive when it is absent.
• MovesLikeMafuyu and Dungeons Perspective are optional and are only needed for their movement compatibility.

Configuration

On first launch with Confluence installed, prefix definitions are written to config/last_one_core/prefixes.json. Edit its item IDs, tags, namespaces, prefix entries, weights, tiers, and modifiers to build your pools. Existing files are not overwritten on later launches.

Other options are in config/last_one_core-common.toml. Prefix attribute replacements use config/last_one_core/prefix_attribute_replacements.json. For multiplayer, keep the shared prefix configuration identical on the server and clients, then restart after editing.

Notes

• Prefixes already present on items are not migrated when attribute mappings change; reforge them to generate updated components.
• The configured target attribute for critical-chance replacement must be registered by another mod.
• This mod is released under the MIT License.

Last One Core（简体中文）

为 Minecraft 1.20.1 Forge 提供可配置的前缀、稀有度与属性工具。

Last One Core 扩展了 Confluence 的物品前缀系统，可通过配置文件编辑前缀池、选择规则和属性映射，控制哪些物品能够获得前缀，以及前缀稀有度和暴击率属性的处理方式。

功能

• 可配置前缀池： 使用物品 ID、物品标签或命名空间筛选物品；编辑前缀等级、权重和属性修饰符。best 选择只从最高等级前缀中抽取。内置近战、远程、魔法、召唤、通用、饰品和护甲分类，也支持自定义分类。
• 护甲前缀： 护甲拥有独立前缀池，可单独配置属性修饰符，不与饰品池混用。
• 掉落物前缀初始化： 可在新物品掉落实体生成时执行 Confluence 的常规一次性前缀初始化。
• 稀有度映射： 将 Confluence 的旧版前缀品质或新版等级映射到 Minecraft 的 Common 至 Mythical 稀有度；Legendary 与 Mythical 的文字颜色可配置。
• 属性替换： 替换新生成或重铸的 Confluence 前缀属性，并可独立替换 Confluence Magic Lib 的全局暴击率属性映射。
• 可选移动兼容： 同时安装 MovesLikeMafuyu 与 Dungeons Perspective 时，翻滚方向会跟随地牢视角的移动方向。

依赖与配置

需要 Minecraft 1.20.1 和 Minecraft Forge（47.2.0 或更高）。Confluence 为可选依赖；未安装时，前缀、稀有度及 Confluence 属性相关功能不会生效。MovesLikeMafuyu 与 Dungeons Perspective 也仅在使用移动兼容功能时需要。

首次安装 Confluence 后，前缀定义会生成到 config/last_one_core/prefixes.json；其他选项位于 config/last_one_core-common.toml，前缀属性替换文件为 config/last_one_core/prefix_attribute_replacements.json。多人游戏时，服务器与客户端的共享前缀配置应保持一致。
