A projectile is any entity not classified as a unit (champion , minion , monster , etc.) that travels at any given velocity and can be blocked by Braum's Unbreakable and destroyed by Yasuo's Wind Wall .
Moving units are not blocked under any circumstance (including dash abilities and units thrown by abilities, such as Force of Will and Roar of the Slayer ). Some champion summoned units will be knocked down by projectile-blocking effects.
Not Blocked
The following effects are described as "falling from the sky" or "emerging from the ground", despite having projectile-like particle/trail effect to indicate velocity. They do not interact with Wind Wall or Unbreakable .
The ranged attacks will bypass Wind Wall / Unbreakable and the non-projectile abilities:
