Raid Boss

Raid Boss is a prismatic augment in League of Legends Arena.

Overview

At the start of the combat phase in each round, you are now imprisoned in the center of the battlefield for 9 seconds, becoming suppression in the duration. While imprisoned, you gain 40 to 70 for 11 damage reduction (including against true damage) and cc-immune, and increase your attack damage, ability power, maximum health, and size according to the time you're imprisoned. At the end of the duration, or upon being damaged to 50% maximum health otherwise, you are set free, airborne all nearby enemies and losing the damage reduction and crowd control immunity but keeping the other bonuses until the end of the round. Additionally, you receive a shield that absorbs damage equal to a percentage of your maximum health and lasts until destroyed.2
