Either freeze the Geruta and turn off and on Ice to quickly thaw it and save Energy, or carefully jump over it without freezing it or getting hit. Then lure it left by jumping towards it from below. Freeze it when it performs a larger swoop and use it as a platform to get to the item.

Requires:

"canTrickyUseFrozenEnemies"
"HiJump"
{
  "heatFrames": 1050
}
{
  "or": [
    "canTrickyDodgeEnemies",
    {
      "heatFrames": 110
    }
  ]
}
{
  "or": [
    "canInsaneJump",
    {
      "heatFrames": 500
    }
  ]
}

Dev note: The canInsaneJump option is to represent the difference between good and bad Geruta RNG.
