Summons

A Summon (also called Summoned Unit, Spawn or Pet) is a unit that is summoned into the game by a Hero.

Gameplay
Altough they are separate from their Hero, but their damage is still credited to their owner. Summons cannot usually collect Experience Globes, but can still directly collect Experience by dealing a killing blow to a Minion.

Some Summons, like Lunara's "Wisp" or Sgt. Hammer's "Spider Mines", can be only killed by a fixed number of damage instances, regardless of damage dealt.

Summons that are not Heroic targets are in the same target priority group as Minions and Mercenaries.

Summon types
Summons are split into following categories:

Active Summons
Active Summons are summoned units that are capable of directly attacking and damaging the enemy. Their Abilities and Basic Attacks deal Spell Damage, and the damage output of both their Attacks and Abilities is enhanced by their owner's Spell Power at the moment they impact. Active Summons Basic Attacks are capable of missing due to Blind and Evade, and can receive buffs and debuffs that are able to target them. When an active Summon damages enemy Heroes under their Forts and Keeps, it will trigger A Call For Help, but the Structure's target priority is redirected to the Summon's owner.

Passive Summons
Passive Summons are summons that do not attack the enemy directly, instead providing some area buffs to your team, like Healing Ward, or debuffs to the enemy, like Rehgar's "Earthbind Totem". Passive Summons are permanently Unstoppable, immune to Skillshots and friendly Abilities and cannot be targeted by Minions and Mercenaries.

Heroic Pets


Heroic Pets are summons that are considered as Heroic targets for many purposes, such as Ability, Talent and quest interactions and being able to collect Experience Globes. Heroic Pets' Basic Attacks deal Physical Damage, like real Heroes, and are capable of missing. Their Abilities deal Spell Damage as normal, but unlike active Summons, they are unaffected by the Spell Power state of their owner and need to be affected by the buff or debuff themselves. When a Heroic Pet damages enemy Heroes under their Forts and Keeps, it will trigger A Call For Help, drawing the Structure's target priority to themself.

Summon figments
Summon figments are permanently Invulnerable summons. As their attacks cannot miss due to Blind or Evasion and because they mostly cannot be interacted with at all by either enemy or allied effects, they could be very well be considered as Spells for vast majority of purposes. Some of them, however, have a "body" of some sort and cannot travel through unpathable terrain or Structures.
