Weather in LumenTale: Memories of Trey is more than set dressing. The world of Talea runs on a day and night cycle paired with shifting weather, and the conditions you see on a map change combat stats, decide which Animon appear, and even gate at least one special evolution. Knowing the full set helps you plan when to hunt, when to fight, and when to evolve.
Quick answer: There are ten weather conditions in LumenTale: Clear, Harsh Sun, Rain, Heavy Rain, Sandstorm, Hail, Rainbow, Fog, Snow, and Ashes Rain. They alter combat stats during battle, control which Animon spawn in an area, and Rainbow weather is required to evolve Minube into Chromaura.

All weather effects in LumenTale
Each map can display its own weather, and the same region can look and behave differently depending on what is active. The table below lists every condition you can encounter in Talea.
| Weather | What it is |
|---|---|
| Clear | Standard fair conditions with no active effect overlay |
| Harsh Sun | Intense sunlight covering the field |
| Rain | Light to moderate rainfall |
| Heavy Rain | A stronger downpour |
| Sandstorm | Blowing sand across the area |
| Hail | Falling ice |
| Rainbow | A rare condition tied to a special evolution |
| Fog | Heavy mist over the map |
| Snow | Snowfall, visible as flakes on the battlefield |
| Ashes Rain | Fire rain, with ash falling from the sky |
How weather changes combat and spawns
Weather feeds directly into the battle system. Active conditions adjust combat stats while a fight plays out, so the same matchup can shift in your favor or against you depending on what is overhead. Because LumenTale builds each species around its own strengths and weaknesses rather than a fixed type chart, weather becomes one more factor to read before you commit a turn.
Weather also decides what you can catch. Certain Animon only appear under specific conditions, which means exploration and capture depend on more than just walking through a map. If a species refuses to show up, the active weather is often the reason, and returning when conditions change can be enough to find it.

Rainbow weather and the Minube evolution
One weather condition has a hard gameplay requirement attached. Rainbow is the trigger for evolving Minube into Chromaura, and it is one of the more involved special evolutions in the game.
Step 1: Collect all six color variants of Minube. Each variant is a separate catch, so this is a collection task before anything else.
Step 2: Place all six Minube variants in your party at the same time. The full set needs to be present for the evolution to register.
Step 3: Trigger the evolution while Rainbow weather is active. With the variants in your party and the correct weather overhead, Minube evolves into Chromaura.
You will know it worked when the evolution sequence plays, and Chromaura appears in your party. If nothing happens, the most common reasons are missing one of the six variants or attempting it under any weather other than Rainbow.

Why weather is worth tracking
Between combat stat shifts, weather-locked spawns, and the Rainbow requirement for Chromaura, the system rewards paying attention to the sky. Talea's weather changes across regions and over time, so checking conditions before you battle, hunt, or evolve saves you from wasted attempts and helps you finish exactly what you set out to do.
