It is safest to pseudoscrew through any acid projectiles. Alternatively, standing on the stairs gives more time to run away.

Requires:

{
  "notable": "Back-Side Fight with Charge and Wave"
}
"Gravity"
"Charge"
"Wave"
{
  "or": [
    "canTrickyJump",
    "Plasma",
    {
      "and": [
        "Spazer",
        "Ice"
      ]
    },
    {
      "and": [
        {
          "or": [
            "canDodgeWhileShooting",
            {
              "enemyDamage": {
                "enemy": "Botwoon 1",
                "type": "acid",
                "hits": 1
              }
            }
          ]
        },
        {
          "enemyDamage": {
            "enemy": "Botwoon 1",
            "type": "acid",
            "hits": 1
          }
        }
      ]
    }
  ]
