Ghost

is a 'non-targeted' summoner spell that makes your Champion move faster and ignore unit collisions with other Champions, minions and monsters for a short period of time.

Strategy
Activation is composed of two components: increased movement speed, and the ability to ignore unit collision. The latter allows you to run through minions, champions and neutral minions.
