4 supers are required to kill Kraid. Only 1 is needed to get him to stand up, after which they are farmable, even though the drop rate is low. Getting up during Phase 2 can be done by jumping on Kraid's projectile platforms or a well timed crouch jump + down grab.

Requires:

{
  "or": [
    {
      "ammo": {
        "type": "Super",
        "count": 5
      }
    },
    {
      "and": [
        {
          "ammo": {
            "type": "Super",
            "count": 4
          }
        },
        "canDodgeWhileShooting"
      ]
    },
    {
      "and": [
        {
          "ammo": {
            "type": "Super",
            "count": 3
          }
