Path of Exile 2

Supports Bow or Spear Projectile Attacks you use yourself. Supported Skills deal lower damage initially, but generate Spectral Projectiles, which deal more damage when they fire. Spectral Projectiles linger and will fire a short duration after no new Spectral Projectiles have been created. Cannot support Channelling Skills, Leaping skills, or skills which rain Projectiles from above.
