Spell indicator

The Spell indicator shows the range of a champion's abilities and its area of effect. It is usually indicated by a blue circle around the champion or a line missile display originating from the champion. Different types of abilities have different indicators. Indicators can be seen simply by hovering over the ability or pressing the ability with no smart cast.

Single target indicator
This is the most simple indicator. It shows a circular range originating from the champion and a target as a cursor. Ground targeted spells don't require a target selected for them to work. The spells are usually single target nukes or chain targeted spells

Some examples: Exceptions:
 * , point-blank AOE after channel
 * , three linear projectiles

Circular AOE
This is a circular indicator showing the spell's area of affect size and the range in which the champion can cast it. This indicator is not used for point-blank spells.

Some examples:

Cone AOE
This indicator shows a cone with its base starting from the champion or pointing at the champion.

Some examples:

Point blank AOE

Concentric AOE

Line missile
