Crouch jump and Spring Ball near the peak of the jump to hit the side of the spikes and boost up onto them. This is also possible from standing on the spikes to avoid the crouch jump. With a very precise spring ball jump, it can also be done without a crouch jump. After getting up onto the spikes, take a second hit from the spikes, hold left, then face right, unmorph, and use either a horizontal damage boost or a couple of blue suit spike jumps to reach the safe platform.

The presence of the Yapping Maws causes Samus to immediately lose i-frames while moving; so the damage boosts must be chained directly from one to the next. This can be done by holding jump the entire time, and releasing right at the end of each boost, to fall straight down for the next boost, facing left the whole time. At the end of the final boost, hold left to boost downward, wait for knockback to expire, then press right to do a buffered turnaround spin jump out of the lava.

The presence of the Yapping Maws causes Samus to immediately lose i-frames while moving; so the damage boosts must be chained directly from one to the next, with the exception of the first. Do the first damage boost from far enough left that Samus can land without bringing the first Yapping Maw on camera; use i-frames to do a spin jump, then chain 4 more damage boosts to cross the room. This can be done by holding jump the entire time, and releasing right at the end of each boost, to fall straight down for the next boost, facing left the whole time. At the end of the final boost, hold left to boost downward, wait for knockback to expire, then press right to do a buffered turnaround spin jump out of the lava.

With each jump, turn and hold left just before landing on the spikes, to get knocked back and down to the right, without damage boosting. Then turnaround spin jump to the right for the next jump.

The presence of the Yapping Maws causes Samus to immediately lose i-frames while moving; so the damage boosts must be chained directly from one to the next. This can be done by holding jump the entire time, and releasing left at the end of each boost to fall straight down for next boost, facing right the whole time. At the end of the final boost, Samus should be out of range of the Yapping Maws, and so should have i-frames to jump normally out of the lava.

Climb up about half a screen. If Phantoon is dead, the last part of the climb should be done carefully to avoid triggering collision with the spikes: Do not press forward or turn-around except while X-Ray is active. For each X-ray stand-up, release the turn-around input quickly to make sure that it is not still held after X-Ray deactivates; alternatively, hold both angle up and angle down to prevent Samus from touching the spikes (though this no longer gives protection if climbing so high that the bottom of Samus' hitbox reaches the spikes). Once Samus is high enough, unequip X-Ray, jump up (from either standing or crouch) to clip past the spikes, and land, taking a single spike hit. Then use the i-frames from the spike hit to run and jump to the left to make it to the door. Samus is high enough after the top of her arm cannon first becomes visible at the bottom of the screen; or up to 3 additional climbs can be performed after that point. In case of an accidental spike collision, it is possible to recover: Unless Samus climbed higher than needed, she will still be stuck in the wall, will take a single spike hit, and be able to continue climbing. With Grapple it is possible to swing on the Grapple blocks, avoiding all spike damage. Spike damage can also be avoided with Space Jump, by doing a stationary turn-around spin jump, which is very precise.

With a blue suit, Samus will instantly lose i-frames, making the spikes very dangerous.

Dev note: FIXME: The canBeVeryPatient is for difficulty placement, as the damageless Space Jump version would likely require many attempts. The resourceCapacity requirement is to ensure that reserve energy management will not be needed for the lower-difficulty version of the strat; this could be refined since suits can affect spike damage, but we don't yet have a good way to represent that cleanly, given that randomizers are likely to modify suit damage protection. The leaveNormally is because the camera will be broken and we don't want to require unreasonable things without being able to reset it.

When the power is on, the floor has spikes (not thorns), and Samus will quickly lose i-frames.

Take a spike hit and pause just after getting hit. Quickly crouch and jump just before the fade out ends. With a precise Gravity jump, it is possible to not need a crouch jump or down grab.

Horizontal damage boost using the spikes. Spin jump to get off the spikes before the leftmost Cacatac comes on-camera.

When the glass is broken, touching Mother Brain from the left will instantly transport Samus to the right. This gives Samus i-frames and knockback but does not cause damage.
