How long do weather events last in Be The Final Boss?

Each weather event lasts 5 minutes, then there is a 10-minute cooldown before the next event begins. The active weather and countdown appear in the bottom-right corner of the HUD.

Which weather event is best for Coins?

Gold Rush — enemies drop 1.75× more coins when defeated for 5 minutes. Pair it with a fast-clear front spawn layout and Throne Power for the highest coin income.

Does Cursed Moon stack with the Double Mutation game pass?

Cursed Moon doubles total mutation chance during its 5-minute window. Community sources report the Double Mutation Chance pass also doubles odds — whether they stack multiplicatively has not been officially confirmed. Test and compare your results.

Where can I see the full event schedule and multipliers?

See the Events page for durations, cooldowns, and confirmed effects, or the Mutations roll guide for summon strategy during Cursed Moon.

Be The Final Boss Weather Events Guide

Use Be The Final Boss weather events correctly: farm Coins during Gold Rush, Fusion Shards during Shard Storm, and mutated units during Cursed Moon.

Quick answer

Weather events are 5-minute server-wide boosts that rotate every 15 minutes. Gold Rush gives 1.75× kill coins, Shard Storm gives 1.3× shard drop chance plus an extra drop attempt per kill, and Cursed Moon doubles mutation chance at the Summon Altar. Match your activity to the active weather and avoid menus during the window.

Step-by-step: use each weather event

1
Check the active weather on the HUD
The current weather and its effect appear in the bottom-right corner of the screen. Each event lasts 5 minutes, followed by a 10-minute cooldown before the next one starts. Use that timer to decide whether to start a farming run or save resources.
The bottom-right tooltip shows the active weather and its effect.
2
Farm Coins during Gold Rush
Gold Rush raises kill coins by 1.75× for 5 minutes and covers the ground in coin drops. Run Auto Battle with a front spawn-kill layout so waves clear quickly and the full window counts.
Gold Rush raises kill coins by 1.75× for five minutes.
3
Farm Fusion Shards during Shard Storm
Shard Storm multiplies shard drop chance by 1.3 and gives each defeated enemy one extra drop attempt. Keep killing waves continuously; more kills mean more drop attempts.
Shard Storm multiplies shard drop chance by 1.3 and adds one extra drop attempt per kill.
4
Roll mutations during Cursed Moon
Cursed Moon doubles total mutation chance for 5 minutes and turns the map purple. Save your Souls and batch Summon Altar rolls during this window instead of rolling randomly outside it.
Cursed Moon doubles mutation chance at the Summon Altar.
5
Plan around the rotation
Events cycle automatically, so prepare before the timer hits zero. Have your farming layout ready for Gold Rush and Shard Storm, and stockpile Souls for Cursed Moon. Doing the wrong activity during a boost wastes the 5-minute window.
