Using movement tricks to reduce fall speed even slightly can avoid touching the sand. A Flatley style turnaround over the grapple block hole reduces fall speed some, but also needs a down back or a tiny jump.

Requires:

"canSuitlessMaridia",
{"disableEquipment": "Gravity"},
"canTrickyJump",
{"or": [
  {"and": [
    "canFlatleyJump",
    {"or": [
      "canInsaneJump",
      "canDownBack"
    ]}
  ]},
  "canWallJump",
  "canResetFallSpeed"
]}

Dev note: The or following canFlatleyJump has no logical relevance but indicates there are two distinct ways of using the flatley jump.
