It's a complete seperate ability from standard auto-attacks.

You press Q once and it will start charging, slowing you by 20% while it does, during which everything else works as normal.

After you want to use the ability, you press Q again in the direction you want to shoot it, the damage of it and how far it travels is based on how long out of the 4 seconds you charge it.

If you wait the full 4 seconds without firing, it will cancel, returning half the mana spent on it and return you to your normal movespeed.
