Damage sources

Damage can be dealt by attacks, abilities and items. Attack damage is the damage dealt per attack, and is displayed on the sword icon in the HUD. Heroes start off with a basic damage plus 1 extra damage per point of primary attribute For a list of heroes sorted by attributes, see Table of hero attributes.   Attributes   Old Abilities     Attributes are the main statistics of all heroes that independently determine most scaling statistics. These . As heroes level up, they gain primary attributes and therefore gain damage. Items that grant increased "Damage" increase attack damage, and do not affect abilities and items. Abilities and items can also deal damage. These are generally fixed.

Attack damage

Attack damage is dealt by regular physical attacks. It is influenced by a couple of factors such as the value of the attack damage Attack damage is the amount of damage a unit is dealing with an unmodified basic attack; the base values are different for every hero.

Spell damage is all damage which is not dealt by physical attacks. This includes all spells which deal magical, physical or pure damage. Even the damage dealt by 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 counts as spell damage, as long as the effect deals its damage in a separate instance from the attack damage.

For heroes, spell damage is amplified based on their intelligence Intelligence is the attribute that grants mana, mana regeneration and spell damage amplification. For each point of intelligence a hero gets: 11 Mana 0.04 Mana regeneration 0.07% Spell damage Additionally, intelligence heroes also get 1 , gaining 1% of amplification per 14 intelligence points (which is 0.07% per intelligence).

Damage classification

All forms of damage in Dota 2 are classified by damage types. There are 3 primary damage types: Physical, Magical, and Pure. Physical Damage can be reduced by Physical Armor or Damage Block, Magical Damage can be reduced by Magical Damage Resistance, while Pure Damage cannot be reduced by either armor or magical damage resistance. All 3 primary damage types have some interaction with other damage-related game mechanics as noted in the table below. Damage may also have the @@@#@@@HP(hp.com)###@### Removal flag, causing the damage to ignore some mechanics which would manipulate it otherwise.

¹ The only exceptions are Moon Glaive and The Swarm, whose damage is blocked.

² These categories only count ability effects which directly manipulate damage, reducing, amplifying or completely blocking them, such as Bloodrage, Bristleback and Refraction.

³ By itself, spell immunity does not interact with any damage type. All spells are rated as to whether or not they can pierce spell immunity independent of their damage type. Thus, spell immunity only governs if a spell has any effect, not how much damage it inflicts. To receive no effects from a spell, the spell must not pierce spell immunity and the target would require both spell immunity and 100% damage reduction of the damage type the spell inflicts. All sources of spell immunity also provide 100% magic resistance to the unit (similar to Fate`s Edict), so a magical damage spell which pierces spell immunity, although technically still fully applying its damage, deals 0 damage to spell immune units, due to the 100% magic resistance it gains from spell immunity. A 0 damage instance is still registered and may proc on-damage effects. If a spell does not pierce spell immunity, then it does not attempt to damage the target in the first place, so that no 0 damage instance occurs.

Physical attack damage

Physical damage can be inflicted by regular attacks from all units (including structures), and by certain abilities. Physical damage is modified by both armor Armor is an attribute shared by all units.

This , and cannot affect ethereal Ethereal, sometimes referred to as ghost form, is a type of status effect that makes a target immune to all physical damage, while also disarming them. It also reduces their magic resistance, causing them to units. The abilities Guardian Angel and Cold Embrace make their targets completely immune to physical damage, although they can still be targeted by attacks and abilities.

Physical spell damage

Physical damage from abilities (and theoretically items) is usually unaffected by armor type, as they are not considered to be attacks. There are some exceptions to this. Be that as it may, if a physical damage ability adds its damage directly to the hero`s attack damage, then it is treated like hero attack damage and thus affected by armor types. The hero attack damage type deals 50% to structure armor type (used by all buildings and siege creeps), and 100% to all other types. They are all affected by armor value, but none by evasion Relationship Between Effective HPTechnology company % and Evasion Evasion is a passive ability that gives the unit a chance to dodge an incoming physical attack.

Magical

Magical Damage is caused primarily by spells, although not all do magic damage. Magic damage is reduced by magic resistance Magic resistance is an attribute of heroes, similar to armor.

This , and deals higher damage against ethereal Ethereal, sometimes referred to as ghost form, is a type of status effect that makes a target immune to all physical damage, while also disarming them. It also reduces their magic resistance, causing them to units. The majority of abilities in Dota 2 deal magical damage.

All abilities not explicitly listed under another damage type section inflict magical damage.

Pure

All heroes, except for Meepo and Visage, possess 25% magic resistance from their armor type.

Be that as it may, it can be reduced or amplified by skills which reduce/amplify every damage type, like Dispersion or Soul Catcher. Pure damage affects spell immune units (since spell immunity does not block damage by itself), but that does not mean that a spell with pure damage can target spell immune units (e.g. Brain Sap deals pure damage, but cannot be cast on spell immune units). It does not affect invulnerable units.

The following abilities deal pure damage:

¹ Mist Coil deals pure damage to the caster, but magical damage to the target.

³ Mystic Snake deals pure damage to units turned into stone by Stone Gaze, and magical damage to all others.

⁴ Whirling Death deals pure damage if it cuts trees within its 300 radius on the same cast, else it deals magical damage.

Flags

Several abilities are flagged certainly, so that they behave differently in certain situations. There are 2 different flags: The HP Removal flag and the No-reflection flag. All spells can be flagged, regardless of what damage type they use.

HP Removal flag

Spells flagged as HP Removal fully ignore any form of damage manipulation (with a few exceptions listed below), means they cannot be amplified, reduced or blocked except by magic resistance in case of magical damage and armor in case of physical damage. They also ignore and do not trigger any on-damage effects, making them unable to cancel consumables for example. Almost every spell flagged as HP Removal deals pure damage. The HP Removal flag also causes damage to ignore invulnerability, be that as it may, this is not always the case.

This flag is usually used on instantly killing effects (this includes expiring summoned as well as with Enchant dominated units, and summons dying due to re-summoning), on spells which damage the caster (as health cost) or as a damage delaying effect.

The following abilities instantly kill units (usually by dealing their current or max health as damage). Their damage type is pure, flagged as HP Removal:

Physical Damage

Physical damage is caused by all standard attacks from units and some spells. All types of physical damage are resisted by Armor. Damage Block reduces damage from standard attacks. Cleave is unaffected by armor value but is still affected by armor type and damage block. Physical damage does not affect Ethereal units. Evasion grants the chance to dodge standard attacks, but will not dodge physical damage caused by a spell.

Attack Types

Physical damage caused by standard attacks can have different attack types depending on the type of unit, and they are affected by different armor types as listed in the table below.

For a comprehensive list, see the Table of Armor and Damage Types

Basic Attack

Basic attacks are used by most creeps and summons. It deals less damage to buildings, siege creeps, and heroes.

Pierce Attack

Pierce attacks are used by some creeps and summons. It deals very high damage to lane creeps and neutral creeps, but very weak damage to buildings, siege creeps, and heroes.

Siege Attack

Siege attacks are used by towers and siege creeps. It deals very high damage to buildings and siege creeps, but less damage to heroes.

Hero Attack

Hero attacks are used by all heroes, and a few special summons. It deals half damage to buildings and siege creeps.

Magical Damage

Magical damage is a very common damage type for spells. Magical damage deals bonus damage to Ethereal units and is affected by Magic Resistance.

Pure Damage

Pure damage is a damage type that is not affected by Armor or Magic Resistance. Pure damage can be reduced and amplified by a few specialized game mechanics.

Non-Damage Types

The following mechanics remove hit points but do not trigger on-hit effects. The underlying mechanic is the damage source not causing a hit. This results in it being ignored by effects which only trigger on hit. A hit is defined as damage greater than 0 from a standard damage type (either physical, magical, or pure). Because the following mechanics do not cause a hit, they are considered Non-Damage Types and are in an entirely different category from standard Damage Types.

HP Cost

HP Cost does not count as damage and is always non-lethal. It cannot be reduced or amplified by anything.

Negative Regeneration

Negative Regeneration does not count as damage but is always lethal. It cannot be reduced or amplified by anything.

Instant Kill

Under certain conditions, some abilities may provide an instant kill. This has no damage type and simply kills the target when the requirements are met. This means that under shared damage effects, instant kill damage is not spread.
