It is possible to kill a Multiviola by the door and pause abuse to grab its Energy drop on G-mode exit. It is important avoid touching the invisible fireballs the Alcoons place, and to prevent them from shooting too many fireballs, as they will eventually prevent drops from appearing. One easy way to do this without any beam upgrades or ammo is to kill them before they jump. This can be done from below by jumping and shooting horizontally near the floor surface. Stay near the far wall when shooting to prevent getting too close and triggering their jump.

Entrance condition:

{
  "comeInWithGMode": {
    "mode": "any",
    "morphed": false
  }
}

Requires:

{
  "or": [
    "h_canCrouchJumpDownGrab",
    "HiJump",
    "canWalljump",
    "SpaceJump",
    "canSpringBallJumpMidAir"
  ]
}
{
  "or": [
    "h_HeatedGModeOpenDifferentDoor",
    {
      "and": [
        "h_heatedGModePauseAbuse",
        "canFarmWhileShooting",
        "canTrickyDodgeEnemies"
      ]
    }
  ]
}

Dev note: Frozen Alcoon platforms and Artificial morph IBJ are not included, as Samus can crouch jump and down grab; they can be considered if G-mode + flash suits are added, though they are still likely not useful. Those are also likely not compatible with preventing the Alcoons from overloading drops.
