                    }
                  }
                }
              }
            }
          }
        ]
      }
    }
  },
  "rewards": {
    "function": "trim_abilities:wild_ability"
  }
}```
 idk why but it doesn't like the entity being "this, attacker, direct_attacker, or attacking_player"
