Monarch in Sol's RNG: Drop Rate, Biome & How to Get It

Monarch cannot be rolled at all under normal skies — it is biome-locked, appearing only under the right conditions at 1 in 3,000,000,000, which makes it one of the hardest Challenged+ pulls in the game.

The gate is the biome itself: watch for the window, then commit every luck boost you have to it. Outside that window, no amount of rolling helps.

Improving your odds

Every luck potion multiplies your effective rate — see the potions & luck guide for exactly how the stacking works. Free potions come from active codes; the full odds table for every aura lives in the aura index.
