Enter with a falling pose in order to be able to spark immediately on entry. This may require a quick drop through the sand in the room above. Sparking very quickly on entry can be used to avoid the Evir projectile.

Entrance condition:

"comeInShinecharged": {},
"comesThroughToilet": "any"

Requires:

{"shineChargeFrames": 10},
"canSuitlessMaridia",
"canShinechargeMovementComplex",
"canHorizontalMidairShinespark",
"canPrepareForNextRoom",
{"or": [
  "canTrickyDodgeEnemies",
  {"enemyDamage": {"enemy": "Evir", "type": "particle", "hits": 1}}
]},
{"shinespark": {"frames": 39, "excessFrames": 16}}

Dev note: Frames are all assuming a toilet entry, frames could be reduced slightly if entering in a more favorable position. While the shinecharge frames could be smaller, this gives a small buffer to orient the direction Samus is facing in the room above. FIXME: It is possible to come in with Gravity and more frames, jump off the sand and pillar, and hero shot spark out the door.
