Damage boost from the neighboring room, to land on the spikes with enough i-frames to run and jump across without taking a spike hit.

The damage boost can be buffered through the transition: face away from the transition, and release all inputs while an enemy hits Samus and knocks her into the transition; hold jump and back through the transition to buffer the damage boost.

Entrance condition:

{
  "comeInWithKnockback": {}
}

Requires:

{
  "notable": "Cross Room Damage Boost"
}
"canDash"
"canUseIFrames"
"canTrickyJump"
