Bounce into the spikes and use a SpeedKeep to run on spikes to setup for a speedball towards the item. A DamageBoost SpeedKeep could be used instead of a Spike SpeedKeep with enough runspeed.

Entrance condition:

{
  "comeInRunning": {
    "speedBooster": true,
    "minTiles": 4
  }
}

Requires:

"canSpeedKeep"
"canCarefulJump"
{
  "canShineCharge": {
    "usedTiles": 21,
    "openEnd": 2
  }
}
"h_speedKeepSpikeHit"
{
  "or": [
    "h_speedKeepSpikeHit",
    {
      "and": [
        "canChainTemporaryBlue",
        "h_speedKeepSpikeHitLeniency"
      ]
    }
  ]
}
"canSpeedball"

Dev note: The extra lenience is because of the need to either to perform a very precise jump off the spikes, or to start with a bounce on the spikes, taking an extra hit.
