If alive, the Metroids do up to 78 damage before the Rinka hits. Entering through the middle of the door will require less damage.

Requires:

{
  "enemyDamage": {
    "enemy": "Rinka",
    "type": "contact",
    "hits": 1
  }
}
{
  "or": [
    "f_KilledMetroidRoom4",
    {
      "metroidFrames": 104
    }
  ]
}
