Some weapons are very slow at killing the Multiviolas and require use of the safe spot in the bottom right Multiviola cage.

Requires:

"h_heatProof",
{"obstaclesCleared": ["F"]},
{"or": [
  {"and": [
    "canDodgeWhileShooting",
    {"enemyKill": {
      "enemies": [["Dessgeega"], ["Dessgeega"], ["Dessgeega"]],
      "excludedWeapons": ["Bombs", "PseudoScrew", "Charge", "Charge+Ice", "Spazer"]
    }}
  ]},
  {"and": [
    "canBeVeryPatient",
    "Charge"
  ]},
  {"and": [
    "canBePatient",
    "Charge",
    "Ice"
  ]},
  {"and": [
    "canBePatient",
    "Spazer"
  ]},
  {"obstaclesCleared": ["C"]}
]},
{"or": [
  {"and": [
    "canCarefulJump",
    {"enemyKill": {
      "enemies": [["Multiviola"], ["Multiviola"]],
      "excludedWeapons": ["Bombs", "PowerBeam"]
    }}
  ]},
  {"enemyDamage": {"enemy": "Multiviola", "type": "contact", "hits": 2}},
  {"obstaclesCleared": ["E"]}
]}

Clears obstacles: C, E

Unlocks doors:

{
  "types": ["missiles"],
  "requires": [{"heatFrames": 30}]
}

Dev note: Bombs are excluded because there is no safe setup. Without canDodgeWhileShooting, tanking the damage and running through is best.
