Because biome-locked auras are only live for the minutes their biome is up, their real difficulty
is much higher than the printed rarity. If you are hunting one, the correct play is to bank your
luck potions and spend them during the biome window rather than between windows.

Two biome lists that disagree
The wiki's biome page and its aura template do not match: the biome page documents Magic, Snow,
Sakura, Rain and Halloween, while the aura template also tags auras to a Galaxy and an Atlantic biome. The tables above are built from
the aura template, because those rows carry rarities that can be checked one by one. Treat the
Halloween biome as seasonal and the Atlantic biome as the newest of the set.
