- The Protector is a Prototroop that does not do any direct damage, but periodically grants crystal shields to friendly troops. These crystal shields work like Dr. Kavan's Ice Shields ability, being able to absorb excess damage, but only apply to one troop at a time.
- The Protector is unlocked for players who have an Armory level of 13 or above. Its level starts 1 level below the Armory level. It can be upgraded using Proto Tokens gained from events.
