Help me modify this code please?

Hi!! Im using a lunatic mode notetag skill from yanfly tricks named "Piercing Shot", this skill checks for the row of the target and damages it and then damages targets with higher rows. I actually want to simplify it, not using rows at all and just making an attack on a target and then hit all remaining enemies for less damage.

This is the code:

<Custom Target Eval>
// Get the target's current row.
var row = target.row();
// Get the target's allies.
var group = target.friendsUnit();
// Loop through each of the rows in your game.
for (var i = row; i <= Yanfly.Param.RowMaximum; ++i) {
  // Get the members of the row's alive members.
  var members = group.rowAliveMembers(i);
  // Check if the member group is larger than 0.
  if (members.length > 0) {
    // Add a random target from that group.
    targets.push(members[Math.floor(Math.random() * members.length)]);
  }
}
</Custom Target Eval>

<Damage Formula>
// Default the chain multiplier to 1.
this._chainmultiplier = this._chainmultiplier || 1.0;
// Calculate the damage formula.
value = user.atk + user.agi;
// Apply multiplier to damage formula.
value *= this._chainmultiplier;
// Reduce the multiplier by 0.15 per target.
this._chainmultiplier -= 0.15;
</Damage Formula>

Thanks!!
