Cold Combination: Ice Crystals' Fortress

This technique combined requires a user of the Water Release and a user of Ice Release (or Freezing Release). Combined, the user of water generates a large dome of water that covers the area to be protected. Then the user of ice (or freezing) freeze the water forming a barrier of ice. Once formed, the ice dome freeze anyone who touch it, as it freezes objects thrown against the same.

The flipside of this technique is that the water user can not withstand the glacial temperature inside the dome and eventually dies. Likewise the user of ice also dies because it uses a huge amount of chakra and has no strength to survive.
