A champion summoned unit (often referred to as a 'pet') is a game character similar to a minion, monster, or champion, that is spawned into the game by a champion.
Leash range
Some champion pets have a radius relative to their source that they cannot surpass. If they go beyond the maximum range, the pet will automatically spawn next to their owner, unless they were being affected by 
Devour or 
Force of Will. The following pets have this mechanic:
Targetable
Decoy
A Decoy is a copy of a champion that is only considered a champion for targeting purposes, otherwise considered a pet. Takedowns also consider it as a pet (exceptions: 
Voracity, 
Evolved Wings, 
Highlander, 
Ravenous Flock and 
Rampant Growth) and its damage is still credited to the owner (and so will attract tower aggro as with any champion damage). Depending on the creation, a decoy can copy almost all effects from the owner, such as item bonuses and current inflicted debuffs.
Interactions with other abilities/runes/items are case by case. For example:
Tahm Kench's Tongue Lash won't apply stacks of An Acquired Taste, but his basic attacks do. He can Devour the decoy and will not get slowed, will have reduced devour time, and will be able to launch it away as a minion. PENDING FOR TEST: Is Tahm Kench's Regurgitate damage capped?
- Blade of the Ruined King has its damage capped while Bloodrazor hasn't.
The damage dealt by a decoy's basic attacks is not considered to be ability damage and so will not trigger spell effects (e.g. spell vamp and 
Luden's Echo). Their attacks will, however, trigger the pet condition of 
Rylai's Crystal Scepter and the healing from 
Hextech Gunblade. Some clones are able to heal themselves with 
life steal if they have any, and Spoils of War will be triggered by clones' attacks.
- Controllable
- The player can control the following champions' movement. This can be done either by
Alt + RMBor via the button used to summon them (such as)
- LeBlanc's Mirror Image
- Deals no damage with its auto attacks but applies some on-hit effects.
- Shaco's Hallucinate
- Explodes on death, damaging nearby enemies.
- Applies any cloned on-hit effects.
- Static
- Illaoi's Test of Spirit
- Does not perform any actions but is vulnerable to damage, which is transferred to its "body" (i.e. the champion).
- Wukong's Decoy
- Mimics some of Wukong's abilities.
- Mimics some of
- Wukong's Nimbus Strike
- Creates two clones that dash to enemies around the target. Untargetable during dash, but become targetable for 0.25 seconds by non-targeted effects after reaching their targets.
- Creates two clones that dash to enemies around the target.
- Neeko's Shapesplitter
- Merely runs in the target direction before timing out.
Minion
Minion designation affects peculiarities such as valid targeting and tower priority. Its damage is credited to the owner.
When a minion attacks:
- If the damage is based on the minion's AD, the damage is not considered to be ability damage and so will not trigger spell effects (e.g. spell vamp and Luden's Echo).
- If the damage is based on the minion's AP, the damage is considered to be ability damage and so will apply spell effects.
In either case, their attacks will trigger the pet condition of Rylai's Crystal Scepter and the healing from Hextech Gunblade.
Additional damage dealt by minions, e.g. 
Heimerdinger's 
H-28G Evolution Turret's laser beam, is considered to be an ability and is classified as ability damage.
- Controllable
- The player can control the following champions' movement. This can be done either by
Alt + RMBor via the button used to summon them (such as)
- Annie's Summon Tibbers
- Tibbers damages enemies around him every second, which is classified as ability damage. Tibbers can gain damage reduction from Molten Shield.
- Tibbers damages enemies around him every second, which is classified as ability damage. Tibbers can gain damage reduction from
- Ivern's Daisy!
- Can be shielded by Triggerseed and will prioritize targets hit by Rootcaller.

- Autonomous
- The following units behave autonomously.
- Elise's Spider Queen
- Heimerdinger's H-28G Evolution Turret and H-28Q Apex Turret
- Turrets periodically fire a laser beam that is classified as ability damage.
- Illaoi's Prophet of an Elder God

- Zyra's Rampant Growth (plant)
Structures / Terrain
The individual units that make up the terrain sometimes have visible health bars (similar to lane minions) in Spectator Mode or briefly upon initially being summoned; and can sometimes be clicked upon to view their Target Frame, offering arbitrary statistical information. Aside from the aforementioned bug, terrain usually cannot be selected as a target directly save for exceptional cases.
Although 
Bard's 
Magical Journey works on terrain, it cannot be created on player-created terrain.
List of abilities affected by terrain:
- Bard's Cosmic Binding
- Camille's Hookshot
- Gnar's GNAR!
- Graves' End of the Line
- Illaoi's Prophet of an Elder God
- Kayn's Shadow Step / Rhaast's Shadow Step / Shadow Assassin's Shadow Step
- Nautilus' Dredge Line
- Ornn's Searing Charge
- Poppy's Heroic Charge
- Sion's Unstoppable Onslaught
- Talon's Assassin's Path
- Taliyah's Rock Surfing
- Vayne's Condemn
- Zoe's Sleepy Trouble Bubble
- Terrain
- Anivia's Crystallize
- Azir's Emperor's Divide
- Will reject enemy attempts to breach the formation, but allows allies to pass.
- Jarvan IV's Cataclysm
- Ornn's Volcanic Rupture
- Taliyah's Weaver's Wall
- Trundle's Pillar of Ice
- Yorick's Dark Procession
- Single-targetable.
- Structures
- Structures can be directly targeted, but otherwise have the same (plus some additional) interactions. Some additional effects include Trample and Tremors.
- Turrets is one type of structure and has some effects that will trigger versus turrets but not other structures, such as Ohmwrecker and Explosive Charge.
- There are currently no examples of champion summoned inhibitors or other non-turret structures, but they are a distinct classification.
Targetable Traps
Traps are triggered when valid targets come into their trigger range. In all existing cases, their damage is classified as ability damage credited to their champion. Traps are initially stealthed after a brief "arm time", and will be revealed by 
Hextech Sweeper and Trap Detection.
Miscellaneous / Wards
The following units have no known classification but can be safely tagged as allied/enemy "units", which makes them valid targets for 
Safeguard and 
Teleport but invalid targets for most other effects (i.e. things that affect minions, champions or any of the above categories). One possible tag for many of the following units is "ward", since wards follow this behavior.
- Gangplank's Powder Keg
- Jarvan IV's Demacian Standard (untargetable)
- Kalista's Sentinel (moves and grants sight only in front of it)
- Rek'Sai's Tunnel (does not grant sight; targetable only by allies)
- Thresh's Dark Passage (affects unit collision)
- Control Ward
- Farsight Ward and Zombie Ward (untargetable by allies)
- Stealth Ward and Totem Ward
- Ghost Poro
Non-targetable
"Non-targetable" refers to units that are never meant to be targetable:
- Azir's Sand Soldiers
- Lissandra's Thralls
- Lulu's Pix
- Fires a bolt from its position independent from Lulu.
- Fires a bolt from its position independent from
- Orianna's Ball
- Shadow Assassin's Blade's Reach
- The shadow that performs the ability in his place is non-targetable.
- Syndra's Dark Sphere
- Yasuo's Dashing Projection
- Zed's Shadows
Non-targetable Traps
Traps are triggered when valid targets come into their trigger range. In all cases, their damage is classified as ability damage and is credited to their champion. If hidden from sight, they will be detected by 
Sweeping Lens' hostile unit detection.
