Repeatedly take damage from a Waver, using the i-frames to avoid taking any spike hits. There are several possible ways to ensure Samus lands on the safe platform: 1) align with the right-most vine of the group of 3 vines in the background; 2) position so that one tile of the doorway ledge is visible on camera; or 3) take an extra Waver hit, to have i-frames while descending the spike stairs.

      }
    },

        {
          "enemyDamage": {
            "enemy": "Waver",
            "type": "contact",
            "hits": 3
          }
        }
      ]
    },

      "and": [
        "canInsaneJump",
        {
          "enemyDamage": {
            "enemy": "Waver",
            "type": "contact",
            "hits": 2
          }
        }
      ]
    }
  ]
}

Dev note: FIXME: account for the possibility of farming the Waver (or all 3) at the end, compensating for some of the damage.
