Upon leaving the Camouflage state, Aamon immediately resets his Basic Attack's cooldown and enhances his Basic Attacks within the next 3s. Each enhanced Basic Attack deals 70 (+100% Total Physical Attack) (+115% Total Magic Power) Magic Damage. The first attack after actively leaving Camouflage is enhanced to deal 84 (+120% Total Physical Attack) (+138% Total Magic Power) damage and reduces all skill cooldowns by 1s.
