UNIQUE Active: Grants a decaying shield to nearby allied champions for 2.5 seconds that absorbs up to 120 (+10 per level) (+20% of your bonus health) damage (120 second cooldown).
Shield per level uses the higher of your level or the target's level. Shield ratio scales with your level. Shield amount is reduced to 25% if the target has been affected by another Locket of the Iron Solari in the last 20 seconds.
