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.
Targetable
Decoy
Decoys are copies of champions that are only considered champions for targeting purposes, otherwise they're considered a pet. Takedowns also consider them as pets (exceptions: 
Get Excited! and 
Evolved Wings) and their damage is still credited to their owner (and so will attract tower aggro as with any champion damage). Depending on the creation, decoys can copy almost all effects like their 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 [R])
- 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
- Deals area of effect damage upon timing out.
- 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-targetted effects after reaching their targets.
- Neeko's Shapesplitter
- Merely runs in the target direction before timing out.
Minion
Minions affects peculiarities such as valid targeting and tower priority. Their damage is credited to their 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.

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

- 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.
- Orianna's Ball
- Shadow Assassin's Shadow
- Syndra's Dark Sphere
- 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.
