Non-targetable

Untargetability is a mechanic that makes the unit untargetable.

Unselectability
Unselectablity makes the unit not selectable, and selectable only in a few cases. Most abilities/items treat unselectable units as if they were invisible, except a few cases. Some sources of unselectability may remove a unit's Hitbox, grant attack immunity, may prevent allies or enemies or both from targeting them.

Although Hide sources also cause the unit to be unselectable and untargetable, they are considered a different mechanic.

Target Unit
While most unit targeting abilities cannot target unselectable units, there are a few particular exceptions.

Spell Reflection sources, and abilities with an instant cast time that does not require facing the target while casting, can fully target unselectability from,  and.

Non-Unit-Targeting Abilities
Additionally, most abilities also treat unselectable units as if they were invisible. Generally, abilities that do not affect invisible units also do not affect unselectable units. This affects the following:
 * neither bounces to invisible units nor unselectable units.
 * neither strikes invisible units nor unselectable units.
 * does not affect unselectable units.

Units spawned by will latch on unselectable units, immediately apply its first damage instance and the armor debuff, and then die after 4 server ticks (0.133s), while completely do not affect invisible units. Against the clone created by, they latch on and work normally.

However, the following abilities do not consider all unselectability sources as invisibility:
