Enter the room with a super sink, in order to clip down to the bottom part of the room. Blindly traverse to the right door. It is recommended to open the door using Grapple if possible, since it can reach the door from a distance even while off-camera whereas beams cannot.

Entrance condition:

{
  "comeInWithSuperSink": {}
}

Requires:

"canOffScreenMovement"
{
  "heatFrames": 360
}
{
  "acidFrames": 345
}
{
  "enemyDamage": {
    "enemy": "Magdollite",
    "type": "contact",
    "hits": 1
  }
}

Exit condition:

{
  "leaveNormally": {}
}

Unlocks doors:

{"types":["missiles"],"requires":[{"acidFrames":75},{"heatFrames":75}]}
{"types":["super"],"requires":[{"acidFrames":25},{"heatFrames":25}]}
{"types":["powerbomb"],"requires":[{"acidFrames":90},{"heatFrames":90}]}

Dev note: FIXME: With better off-camera movement, this can be done with significantly less damage (and with Gravity the Magdollite hit can also be avoided); but after the supersink setup it's not clear if it's reasonable to assume any more than this. FIXME: If the acid is already drained, then the requirements here could be reduced (though in that case there's not as much reason to do this strat).
