Earth-style ninjutsu: spines of the earth.

(...continued from "How did you get here?"...)

Being taunted by the guardian wraith that all her skills were smoke and mirrors, Karo proves it wrong with collecting a large amount of chakra with her body(yes it is a little bit clear where )...
  Spines of the earth summons forth a ring of outward jagged stone spines that erupt from the ground around the summoner. Used normally for close range personal defense against multiple opponents. Can be used to provide limited cover until the spines are dismissed.

 Originally was going to have a few of the wraiths impaled on the spines, but couldn't get them to look right .-shifter
