Attributes

 

Old Abilities

 

Attributes are the main statistics of all heroes that independently determine most scaling statistics. These attributes are strength, agility, and intelligence. Attributes are gained when a hero levels up, obtains a talent, buys certain items, or uses certain abilities. Illusions benefit from attributes.

Primary attribute

Every hero has a primary attribute, which controls their attack damage. Every point in their primary attribute adds 1 point of damage to their attacks. A hero's primary attribute heavily impacts and commonly even defines the hero's role and how they are played. For example, intelligence heroes are typically more dependent on abilities. A hero's primary attribute typically grows faster than the other two attributes.

The following abilities can change a hero's primary attribute

• Morphling - Morph
  
  Duration: ( )
  Copies the target hero's primary attribute while active.

Strength

Main Article: Strength

Strength is a measure of a hero's toughness and endurance. Strength determines a hero's maximum health and health regeneration. Heroes with strength as their primary attribute can be hard to kill, so they often take initiator and tank roles, initiating fights and taking most of the damage from enemy attacks.

Every point in strength increases:

• Maximum health by 20.
• Health regeneration by 0.1.

For strength heroes, every point in strength also increases attack damage by 1.

Agility

Main Article: Agility

Agility is a measure of a hero's swiftness and dexterity. Agility determines a hero's armor and attack speed. Heroes with agility as their primary attribute tend to be more dependent on their physical attacks and items, and are usually capable of falling back on their abilities in a pinch. Agility heroes often take carry and Gank roles.

Every point in agility increases:

• Armor by 0.17.
• Attack speed by 1.

For agility heroes, every point in agility also increases attack damage by 1.

Intelligence

Main Article: Intelligence

Intelligence is a measure of a hero's wit and wisdom. Intelligence determines a hero's maximum mana and mana regeneration. Heroes with intelligence as their primary attribute tend to rely on their abilities to deal damage or help others. Intelligence heroes often take support, gank, and pusher roles.

Every point in intelligence increases:

• Maximum mana by 12.
• Mana regeneration by 0.05.

For intelligence heroes, every point in intelligence also increases attack damage by 1.

Items granting attributes

Each attribute has its own set of items that focus on boosting it. These items are different for each attribute. In order to categorize them, they're split into 5 different sections:

• Small Items boost their associated attribute by 3, or all attributes by 1. These items are usually taken as starting items to make up for gaps in a hero's statistics.
• Medium Items boost their associated attribute by 6, or all attributes by 2. Though generally not taken to increase attributes, these items are usually components of many midrange items.
• Large Items boost their associated attribute by 10, or all attributes by 4. These items are usually components in more powerful items, and almost never bought just for the stats.
• Ultimate Items boost their associated attribute by 25, or all attributes by 10. These are mostly used to make late game items because of how expensive they are and how cost-ineffective they are per point of stats.
• Besides the items in the table, Ghost Scepter is another basic item that boosts all attributes by 5. All other items that grant attributes are upgrades, and are all derived from one or multiple of the 16 items listed below.

	Small	Medium	Large	Ultimate
All Attributes	Iron Branch + All Attributes	Circlet + All Attributes	Crown + All Attributes	Ultimate Orb + All Attributes
Strength	Gauntlets of Strength + Strength	Belt of Strength + Strength	Ogre Axe + Strength	Reaver + Strength
Agility	Slippers of Agility + Agility	Band of Elvenskin + Agility	Blade of Alacrity + Agility	Eaglesong + Agility
Intelligence	Mantle of Intelligence + Intelligence	Robe of the Magi + Intelligence	Staff of Wizardry + Intelligence	Mystic Staff + Intelligence

Talents granting attributes

Several heroes have talents which directly grant them a boost on one or more attributes. There are talents for each of the 3 attributes, and talents for all attributes together. There are no talents for 2 out of 3 attributes, but a hero may have two separate talents for different attributes, which are usually provided as a choice on the same level, so the player may decide between one of them.

All Stats	+5 +5	+5 +5				+8 +8
