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": {

              [
                "Dessgeega"
              ],
              [

Unlocks doors:

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