Con Catalyzed Nanobots T3

When healing an ally whose health is below 20%, nanobots in the player's blood activate, causing their healing spells for the next 20 seconds to generate a shield equal to 150% of the healing done for 10 seconds. The shield can stack but cannot exceed 100% of the target’s Maximum Health. After activation, time is required to produce new nanobots. Cooldown: 3 minutes.
