Crystal Flashing on the Zebbo spawner will usually not deal enough damage to Samus to trigger reserves. One way to make this fairly reliable is to kill the Yapping Maw then take a Zebbo hit while on its spawner, and then place the Power Bomb such that it explodes and kills a Zebbo shortly after it spawns. Samus will then pick up the drop and start Crystal Flashing where her refill is usually in a good rhythm for the Zebbo to be able to trigger reserves. There is an approximate 2/3 chance of success.

This can only be done suitless and with no E-Tanks.

While in the morph tunnel, simply unmorph to break the bomb blocks overhead.

Requires:

{"haveBlueSuit": {}},
"Morph"

Clears obstacles: E

Break the tunnel block with a Bomb and then return to safety. Break the runway block on the next cycle. SpringBall helps avoid acid damage. Bombing Samus up through the runway with a second Bomb can help, or it can trap Samus in the acid if liquid physics take effect.

Requires:

"h_useMorphBombs",
{"or": [
  "h_useSpringBall",
  {"acidFrames": 10}
]},
{"or": [
  "canInsaneJump",
  {"and": [

Dev note: Damageless is possible without SpringBall but it is very likely you end up taking more damage by attempting it.
