At the Start of the game, Austin gains his mobile probe companion that attacks with him in-combat that has it's own targets and responds with a transformation everytime Austin change the stance of his probe.
His Probe attacks in three different ways according the stance he is currently using.
Flight Stance: His probe attacks a single target trice per second dealing true damage.
Blimp Stance: His Probe attacks as a linear skill shot that travels toward it's target dealing magic damage. Attacks as fast as Austin's attackspeed.
Rocket Stance: His probe attacks by firing 3 rockets for every 2 seconds up to 3 available targets, each dealing physical damage. Consecutive rocket taken by a single target deals 50% less from the other rockets.
His probe's damage depends on his 3 basic abilities and does not applies on-hit and on-spell effects.
Active He fires a rocket in a line that deals physical damage to the first enemy hit. If he hits an enemy champion, his probe mimics the cast by firing a rocket toward the enemy champion dealing 50% of the damage.
