Observe before spending
Weather may be visual, event-related, or tied to a later system. Check the current game’s prompts and changes before spending a rare resource around it.
Log the useful details
Note the weather type, start time, map area, active upgrades, and any changed rewards. A short repeatable log is more useful than a guess.
Expect updates to change it
TBOD² is actively updated, so an older weather explanation can become wrong. Prefer the current Roblox description and in-game notices.
