Cobblemon KageBattleUI

KageBattleUI rebuilds the Cobblemon battle screen around the information players need most: move effectiveness, estimated damage, field conditions, stat changes, target selection, switching decisions, and a battle history that is easy to follow.

It works as a client-side mod. Installing the same JAR on a server is optional and enables authoritative duration data for supported weather, terrain, and screen effects.

Why use KageBattleUI?

Smarter move decisions
See type effectiveness, conditional damage ranges, current-HP KO estimates, PP, accuracy, priority, STAB, known field modifiers, and official move descriptions before choosing.

A battle history you can actually follow
Player and opponent actions are clearly separated with readable turn markers, damage results, stat events, and hoverable move or Ability information. The panel can be moved, resized, and customized.

Clear target selection
Target cards include form-aware Pokémon portraits, current HP, typing, and complete effectiveness wording. Neon outlines show exactly which Pokémon will be affected by single-target, spread, ally, and full-field moves.

Better switching information
Hover a party member to inspect its current stats, types, held item, Ability, moveset, effectiveness against each active opponent, and defensive matchup.

Field awareness
Track weather, terrain, Trick Room, Tailwind, screens, hazards, visible stat stages, and remaining turns when the duration is known.

Singles, doubles, and spectating
The interface supports both battle formats and includes a dedicated spectator presentation with trainer identities, team colors, visible HP, and an easy-to-follow action feed.

Move details and damage guidance

Hovering a move opens a compact information card containing:

• The official localized move description.
• Published secondary-effect chances when available.
• Target-by-target effectiveness and estimated damage.
• Dynamic OHKO, 2HKO, and 3HKO guidance based on visible current HP.
• Known modifiers such as STAB, weather, screens, burn, and spread reduction.
• A clear explanation when a move is unavailable, including Choice-item locks and zero PP.

Useful information without revealing hidden data

KageBattleUI does not expose an opponent’s exact IVs, EVs, held item, or selected hidden Ability. Opponent stat displays are legal possible ranges derived from public species and form data together with visible battle information.

Damage previews are decision aids rather than guarantees. Hidden Abilities or items, critical hits, variable-power moves, multi-hit moves, accuracy, custom server mechanics, and other unresolved effects can change the real result.

Make the interface yours

The metal cog opens 52 persistent settings, including:

• 16 complete themes and 48 named colors.
• Separate colors for Battle History, the HUD, information cards, Ability announcements, action tiles, the player, allies, and opponents.
• Five font profiles plus saturation, brightness, opacity, border, corner, shadow, and motion controls.
• Battle-log density, text size, labels, target layout, spacing, dividers, filters, position, and size.
• Held-item, type-icon, gender-icon, KO-estimate, damage-note, switch-advice, and Ability-animation options.

Preferences save automatically and remain after relogging.

Installation

Requirements

• Minecraft 1.21.1
• Fabric Loader
• Fabric API
• Cobblemon 1.8.x

Client installation

1. Install Fabric Loader, Fabric API, and Cobblemon.
2. Place the KageBattleUI JAR in your mods folder.
3. Start Minecraft and enter a Cobblemon battle.

KageBattleUI works client-side, so a server does not need the mod for the interface to function.

Optional server support
Server owners may install the same KageBattleUI JAR to provide exact, extender-aware duration packets for supported weather, terrain, and screen effects. Players without KageBattleUI can still join normally; they simply do not receive the custom interface or Kage timer data.

Controls

• Metal cog: Open customization.
• Drag the thin top rail: Move Battle History.
• Drag the bottom-left grip: Resize Battle History.
• L: Optional compact, expanded, or hidden Battle History shortcut.
• I: Show or hide Battle Intel.

Keybinds can be changed in Minecraft Controls.

Important notes

• KageBattleUI is a battle interface and decision aid, not a complete battle simulator.
• When an authoritative field duration is unavailable, the UI displays a question mark instead of guessing.
• The stock Cobblemon message pane may still appear when the entire battle GUI is minimized.
• This release candidate should be tested with your preferred GUI scale and server modpack before competitive use.
