Drop Rate Plugin

Instantly see the exact drop rate of items when monsters or bosses drop them, without leaving the game.

Created by Pluckss.

Behind the Scenes

This plugin started after I accidentally disassembled my Group Ironman's only Toxic blowpipe and had to grind out a replacement.

During that grind, I kept seeing dragonstone drops and repeatedly checking the rate in the wiki, even though I already knew it.

That frustration sparked the idea: show drop rates directly in chat so the information is always there when you need it.

Example

Features

• Shows a chat message when a dropped item has a known drop rate.
• Supports standard rates like 1/128 and bundle rates like 6/378 or 12/378.
• Uses color-coded chat messages to quickly separate common, uncommon, and rare drops.
• Adds a purple ultra-rare tier for especially rare drops.
• Each tier color can be customized with a color picker.
• Colors and rarity checks are based on the effective chance of the drop, including bundle drops.
• Lets you keep the raw wiki rate, convert it to an effective 1/x, or show both in chat.
• Can optionally append a rounded percentage such as 1/100 (1%) or 4/51 (7.84%).
• Can optionally show source hints for ambiguous drops like Normal 1/400 | RDT 1/5012.5.
• Lets you customize the color tier cutoffs or switch everything to neutral white text.
• Works with drop data whether it is stored as NPC -> item or item -> NPC.
• Supports both normal drop tables and the Rare Drop Table (RDT) with automatic dual lookup.
• Supports context-aware overrides for exceptions like task-based Hydra rates.
• Includes cleaner feed options so players can reduce chat clutter.

Display

• Drop visibility Choose between All drops, Cleaner feed, or Rare drops only.
• Rate display Defaults to Raw wiki rate. You can switch to Effective 1/x to convert rates like 2/222 into 1/111, or Raw + effective to show both.
• Show percentage Off by default. Adds a rounded percent chance to the end of the message.
• Show source hints Adds extra context for drops that can come from more than one table, such as both normal and RDT rates.
• Rare-only minimum rate Used only in Rare drops only mode. Example: 700 means show 1/700 and rarer.

Filtering

• Show bundle drops Includes common multi-roll or bundled drops such as 4/115, 6/378, or 12/378.
• Hidden filler items Lets you hide custom filler items in Cleaner feed mode with a comma-separated list.

Appearance

• Color style Choose between Tiered colors and Neutral white.
• Common tier max Tiered colors only. Rates up to this value use the common color.
• Rare tier minimum Tiered colors only. Rates at or above this value use the rare color.
• Ultra-rare tier minimum Tiered colors only. Rates at or above this value use the ultra-rare color.
• Common color Pick the color used for common-tier drops.
• Uncommon color Pick the color used for uncommon-tier drops.
• Rare color Pick the color used for rare-tier drops.
• Ultra-rare color Pick the color used for ultra-rare-tier drops.

Useful Notes

• The plugin reads normal drop data from src/main/resources/droprates_clean.json at startup.
• Rare Drop Table data is loaded from src/main/resources/rare_drop_table.json.
• Extra context rules and alternate-table metadata live in src/main/resources/drop_metadata.json.
• If an item exists in both the normal table and the RDT for the same NPC, and Show source hints is on, both rates are shown side by side.
• If an item and NPC combination is not in either database, no drop-rate message is shown.
• Messages appear in chat as Quantity x Item (rate).
• Raids are not currently supported.
