Quick cast

The Smart Cast is a characteristic of some abilities in League of Legends.

Gameplay
It automatically casts the selected ability at the current mouse cursor position as if you had first pressed the ability button and then left-clicked at the target position. Smart cast works for self-buffs abilities, targeted abilities, ground targeted abilities and skillshots. Smartcasting an ability that can be cast on self (eg, a shield or an heal) when the cursor is on an invalid cast will self-cast the ability instead.
