Quadruple Cloud

The Quadruple Cloud is a boss created by the Puppet Master in Prodigy 2. It's a clump of uncatchable clouds the you have to battle separately.

Skywatch
In Skywatch, you have to battle Rainy Storm, then Sandy Storm, and last, Frosty Storm. You then have a short confrontation with Stormy Storm. The four clouds all combine into the Quadruple Cloud. It uses the Storm, Water, Ice, and Shadow Element. Stormy Storm uses the Shadow Element, Rainy Storm uses Water, Sandy Storm uses Storm, and Frosty Storm uses Ice. While in "separate battles '', all of the clouds only use Storm. While in the short confrontation with Stormy Storm, it uses the Shadow element. When combined, the cloud uses every spell (even Epic Attacks and Boss-Only Attacks) in the Water, Ice, Storm, and Shadow elements. That means it can use Ink Blot and even Astral spells.

Areas
Following the Quadruple Cloud's apparent defeat, you can play Prodigy 2's other zones. But beware! Quadruple Cloud is never officially defeated. Although you do get the Skywatch Gem for defeating it the first time it will frequently force you to fight it by popping up randomly in areas. It has no weaknesses. It is neutral against Astral and is Strong/Neutral to every other element depending on what spell it casts and what cloud casts it.

The Fight Itself (combined)
During fights, it has an advantage over every pet. That is because it has a very advanced AI by recognizing the element. If the element is anything other than Astral, it only uses the Shadow element. If it is Astral, it uses Ice, Water, Storm, and Shadow spells randomly.
