How to make attack modifiers for melee units?. like an attack modifier that can be autocast, if the attack lands it reduce the enemy armor.

Here are some passive skills that use your attack. They can work for either melee or ranged since there's not really any difference.

Here's a passive ability with a 25% chance to proc and deal 100 spell damage:

• Lightning Strike Attack
  • Events
    • Unit - A unit Takes damage
  • Conditions
    • (Level of Lightning Strike for (Damage source)) Greater than 0
    • (Damage From Normal Attack) Equal to True
    • (Random integer number between 1 and 100) Less than or equal to 25
  • Actions
    • Special Effect - Create a special effect attached to the origin of (Damage Target) using Abilities\Spells\Other\Monsoon\MonsoonBoltTarget.mdl
    • Special Effect - Destroy (Last created special effect)
    • Unit - Cause (Damage source) to damage (Damage Target), dealing 100.00 damage of attack type Spells and damage type Normal

Here's a toggle ability based on Searing Arrows which causes all attacks to reduce armor while toggled on:

• Piercing Blow Attack
  • Events
    • Unit - A unit Takes damage
  • Conditions
    • (Level of Piercing Blow for (Damage source)) Greater than 0
    • (Damage From Normal Attack) Equal to True
    • ((Damage source) is in PiercingBlowGroup.) Equal to True
  • Actions
    • Unit - Create 1 Dummy for (Owner of (Damage source)) at (Position of (Damage Target)) facing Default building facing degrees
    • Unit - Add a 0.20 second Generic expiration timer to (Last created unit)
    • Unit - Add Inner Fire (Piercing Blow Armor Reduction) to (Last created unit)
    • Unit - Order (Last created unit) to Human Priest - Inner Fire (Damage Target)

Inner Fire is setup to target enemy units and has a negative armor bonus so it reduces armor.

Here's how to manage the toggling of the ability so it can turn on and off properly:

• Piercing Blow Toggle
  • Events
    • Unit - A unit Is issued an order with no target
  • Conditions
    • (Level of Piercing Blow for (Triggering unit)) Greater than 0
  • Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Issued order) Equal to (Order(flamingarrows))
      • Then - Actions
        • Unit Group - Add (Triggering unit) to PiercingBlowGroup
      • Else - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • (Issued order) Equal to (Order(unflamingarrows))
          • Then - Actions
            • Unit Group - Remove (Triggering unit) from PiercingBlowGroup.
          • Else - Actions

These triggers have memory leaks and other poor design choices but they show you how to get started. Also, you'll need to be on patch 1.31+ to use the Takes Damage event. Otherwise, you can rely on a Damage Engine system that's compatible with an older version (search Hive for one) and use that system instead.

Thank you. I will maybe try Bribe's damage engine since I only use War3 1.31.1.

Also, I really appreciate that you answered all my questions about triggers.

Edit: so i download bribe's damage engine and i copy/paste it to my map and i'm trying to make the Searing arrows ability that you made but i don't know the trigger "Damage from Normal Attack". Also i replaced the "a unit takes damage" with "a unit is attacked" will that work?
