Enter with a precise run speed to jump (after the transition) and reach the far left ledge. With 7 tiles of runway, jump at the start of the sloped tiles to avoid the Skultera and reach the ledge.

The working ranges are a runway of 7 tiles with an open end to 8 tiles without an open end or 12 tiles with an open end to 13 tiles without an open end. The 12 tile runway is more lenient and can sometimes be set up easily, if the neighboring room is 1 screen wide, by moonwalking against a closed door on the opposite side of the room. The 12 tile setup also avoids the risk of clipping the Skultera.

Entrance condition:

"comeInRunning": {
  "speedBooster": "yes",
  "minTiles": 7
}

Requires:

"canSpeedyJump",
"canCrossRoomJumpIntoWater",
"canTrickyJump"

Dev note: This is not technically a canCrossRoomJumpIntoWater, but it is used here because of the way the momentum changes as Samus enters the water. FIXME: This is technically a lenient canTrickyDashJump, but until a tech like that is made, canTrickyJump is used here for difficulty placement.
