Unique Attack Modifier


Info

Unique Attack Modifiers (abbreviated UAM; formerly known as Orb Effects) are special attack modifiers Attack modifiers are modifiers which apply an effect to a unit s basic attacks. These effects can widely vary, from healing, to damaging or even disabling effects. Most of these modifiers have their own rules. For dota2 that cannot be used simultaneously with each other⃢₀ₔone always takes priority. They may be provided by abilities (e.g. Anti-Mage`s Mana Break), or items (e.g. Morbid Mask   Item   Changelogs     Morbid MaskBL A mask that drains the energy of those caught in its gaze.

Unique attack modifiers do work simultaneously with non-unique attack modifiers.

Priority

Multiple unique attack modifiers do not stack. One always takes priority, as follows:

  1. Unique active attack modifiers Attack modifiers are modifiers which apply an effect to a unit s basic attacks. These effects can widely vary, from healing, to damaging or even disabling effects. Most of these modifiers have their own rules. For dota2 that were cast manually.
  2. Unique active attack modifiers set to auto-cast.
  3. Unique attack modifiers granted by items.

Unique Attack Modifier Stacking

Unique Attack Modifiers function on a system of priority, because Unique Attack Modifiers do not stack. For each attack only one Unique Attack Modifier will be applied.

  1. Conditional Modifiers are applied first: these are Unique Attack Modifiers that only occur on some attacks and are not controlled by the player, such as the chance based Mjollnir. If a Conditional Modifier fails to occur then an Item or Ability Modifier will be present on the attack if applicable.
  2. Ability Modifiers are applied second: these are Unique Attack Modifiers that are applied by hero abilities. Note that Conditional Modifiers will only override an Ability Modifier if the Ability Modifier is casted using autocast. If casted manually, the Ability Modifier will always take effect.
  3. Item Modifiers are applied last. The oldest item in the hero`s inventory will have priority. Priority can be changed by dropping the item with the unwanted effect out of the inventory, and then picking it up again.

Exceptions

While still following the rules above, Eye of Skadi will stack with any type of lifesteal. This is the only case of Unique Attack Modifiers stacking.

While normally illusions do not inherit attack buffs from items, illusions will get Diffusal Blade`s Manabreak passive applied to their attacks. This makes Diffusal Blade a strong option on illusion heroes.

Orb Walking

The technique known as Orb Walking is a mechanic that exploits the game`s aggro system to allow a hero to harass safely in lane without drawing creep attention. If a hero auto attacks using auto-cast, the hero will be attacked by enemy creeps and towers nearby. However when a hero casts a spell, this attention is not drawn and the creeps will not attack. Since manually casting a UAM such as Drow Ranger`s Frost Arrows counts as a "spell cast" to creeps and not an auto attack, it fools the creeps. Heroes with auto-castable attack modifiers can safely harass enemies this way, making more efficient damage trades against the enemy in lane.
