Spell Reflection

Main Article: 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.

Instant Attack
