Immobilizing an enemy champion will cause 3 glacial rays to emanate from them towards you and other nearby champions, creating frozen zones for 3 (+ the immobilizing effect's duration) seconds that slow enemies for 20% (+90% per 100% Heal and Shield Power) (+6% per 100 Ability Power) (+7% per 100 bonus Attack Damage) and reduce their damage by 15% against your allies (not including yourself).
