Spell Reflection

The reflected abilities are akin to the reflecting hero casting the abilities back to the enemies, with an instant cast time and without getting interrupted. The scaling values of reflected abilities are based on the reflecting hero's stats, and not on the original caster's. Therefore, projectile-based abilities are usually reflected if the affected target has a projectile speed upon impact. Heroes that have a projectile speed of 0 do not reflect any abilities.

Heroes

Heroes have an average projectile speed of 1,046.
