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.

Attack damage is dealt by regular physical attacks.

Spell damage

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 dota2 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 dota2 , 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.

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. Armor is used to determine the amount of damage reduction (or amplification if an armor value is negative) a unit takes from physical damage sources.

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.

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.

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

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.

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:

Time and Cost

All abilities have a cast time and cost, along with a cooldown.

Cast Time

Abilities use either the hero`s cast time or its own unique cast time. The animation can be cancelled early to stop the ability from being used, and it will not spend Mana or go on cooldown if cancelled.

Instant Cast Time

Ignores cast time and activates instantly.

Channel Time

Will only provide its effect as long as the user does not get interrupted or cancel it early. Some forms of movement do not interrupt channeling.

Cooldown

The wait period after casting. The spell may not be allowed to be cast again until the cooldown time is over.

Mana Cost

Requires Mana Points to be spent from your hero`s mana pool. It cannot be cast without enough mana.

HP Cost

HP cost was previously known as HP removal. It directly subtracts the Hit Points of the user and does not count as damage or an attack. This allows effects that are stopped by on-hit triggers such as Bottle to continue working. HP cost is not considered a damage type, is always non-lethal, and cannot lower the user`s HP below 1. The damage cannot be reduced or amplified by any ability. Below is a list of all spells with HP costs.

Charges

Main Article: Charge Abilities

Charge based abilities use an ammo system rather than a basic single-use cooldown ability. Each charge recovers on a shared cooldown, allowing only 1 charge can be recharged at a time. Another charge does not recharge until the one before it has finished. Charge an be stored to allow multiple uses in quick succession. The maximum number of charges depends on the ability.

Targeting Types

Some spells require a target to be cast, while other spells are released instantly.

No Target

Skills of this type do not require a target to be cast, and will activate when pressed. Skills of this type will start their effects as soon as their cast time or channel time has completed.

Unit Target

Skills of this type require a target to be selected to provide their effects. The cursor will change to allow target selection. If the spell has an area of effect, a blue visual indicator appears. The indicator has a central targeting visual to imply that it must be cast on a single target regardless of the area effect it provides after.

Control Modifiers
A few Consumables can be changed to Unit Targeting when the Control key is held. List is below:

Point Target

Skills of this type require an area to be selected and may affect the area around the casting point. If the spell has an area of effect, a blue visual indicator appears to indicate the area that will be affected.

Ability Types

Active

Active abilities must be used in order to apply their effects. Active abilities can consume mana, cooldowns, and usually have some method of targeting related to them. Most abilities are active abilities. Active abilities are indicated by a bevel around the icon, which makes them look like a pressable button. They can be activated by pressing their associated hotkey.

Channel

Main Article: Channel

Channeled abilities require the user to stay still while it is active. A bar showing the duration of the channel time will appear when used. The effect ends if interrupted or cancelled. See the main article for a list of all channeled abilities and actives which can be used while channeling.

Passive

Main Article: Passive

Passive abilities will apply their effects as long as they are learned. They can be applied to the hero itself, or as an aura belonging to the hero. Passive abilities do not consume mana and sometimes have cooldowns.

Toggle

Main Article: Toggle

Toggled abilities can change states between on and off. They are similar to passives but must be toggled to enable or disable their effects. Toggled abilities do not have cooldowns and sometimes consume mana.

Auto-Cast

Main Article: Auto-Cast

Auto-Cast abilities are abilities that can be toggled on to automatically cast, or turned off to manually cast. An auto-castable ability will have an empty rim around it, which glows orange when toggled on. When toggled on the ability will apply when it can. For example, Drow Ranger`s Frost Arrows will be used whenever she attacks a valid target. When attacking an invalid target such as a Tower, the Frost Arrows will not be used or consume mana, as if they are toggled off. These abilities can also be manually cast for greater precision, in which case they fire off a single time. If the ability is a Unique Attack Modifier it will be treated as a spell when manually cast, as opposed to a physical attack. This is known as Orb Walking. See here for a list of all auto-cast abilities.

Innate

An innate ability is a special ability that is not skilled and is already learned by the hero at the start of the game. This persists through all game modes, including Ability Draft. While their other skills may be shuffled around, a hero with an innate ability will still have their innate ability tied to them alone. All innate abilities are listed below:

Ultimates

Ultimate abilities are high impact abilities that may only be leveled 3 times instead of 4. They may be leveled at 6, 12, and 18 at the earliest. Some ultimates are affected by Aghanim`s Scepter, a powerful item that passively upgrades them. If dropped or sold, the upgrade is lost until the hero is in possession of it again. Upgrades with irreversible effects will not allow Aghanim`s Scepter to be removed from that hero`s inventory. The upgrade Aghanim`s Scepter provides is different for every hero. It can be a new ability entirely, an upgrade to the hero`s basic abilities, or simply an increase in power to the hero`s ultimate.
