The Water Realm, also known as Water Island, is the Water elemental island in the Second Dimension. It is a floating island mostly taken over by an enormous lake and many rivers with crystals in the bottom, with the little land left being rocky mountains and beaches. It appears to have settlements and docks, and most interestingly giant temple-like aquariums right next to the waters. It was taken over by Chill Bill and his minions in Skylanders: Battlecast.
Missions - Tides of Kaos
Conditions - Fire Skylanders deal 10+ damage. Water Skylanders gain 30+ max health.
The conditions of this mission apply to all other Water Realm missions.
Pour It On
Conditions - At the start of the turn, the active character receives -10 power and loses 10 health.
A creature that resembles a shark or seal is always in the background of battles taking place in the Water Realm, occasionally jumping out of its rock for a swim.
Old versions of the game had Buzz mention using the island's healing hot springs during his vacation and several times caused the missions' conditions. However, the final version removes such references as the level's difficulty was increased, and the effects are instead changed to damage from torrential rain.
The card art for this Realm's mission select is Chill Axe.
