The only projectiles that Kraid can hit Samus with through the transition are the spinning talons after he stands up. This requires Kraid to not be defeated and the door to be open during the second phase.

Requires:

{
  "not": "f_DefeatedKraid"
}
"canRiskPermanentLossOfAccess"
{
  "or": [
    "Charge",
    {
      "ammo": {
        "type": "Missile",
        "count": 2
      }
    },
    {
      "ammo": {
        "type": "Super",
        "count": 1
      }
    }
  ]
}

Exit condition:

{
  "leaveWithGModeSetup": {}
}
