This can be a very long fight if Crocomire is stingy with the farming phases. Farming requires careful dodging in order to minimize energy drops. Delay grabbing all of the drops until necessary to reduce the chance of running out of ammo.

Requires:

{
  "notable": "Crocomire with 5 Missiles"
}
"canFarmWhileShooting"
"canBePatient"
{
  "or": [
    {
      "ammo": {
        "type": "Missile",
        "count": 2
      }
    },
    {
      "ammo": {
        "type": "Super",
        "count": 2
      }
    }
  ]
}
{
  "resourceCapacity": [
    {
      "type": "Missile",
      "count": 5
    }
  ]
}

Dev note: This strat is notable, not because it's harder than its required tech, but because its tedious, RNG heavy, and players might not want to encounter it. Crocomire does not have a farming phase until he has been hit twice. It is possible to get to the farming phase with 1 PB, but sometimes Croc will just rush Samus into the spikes without ever having farm phases, so it is ignored here.
