Zealot is an Item that can be found within common locations, including choice enemy Camps, given by Spouses, and rarely as a reward from Seasonal Festivals. Upon being picked up, there will always be a chance for a random ally in the player's immediate vicinity to become energized once an Enemy is killed. This can make Zealot especially useful while clearing Camps while the player has Drones or is married to certain Spouses, as they can become energized and more efficient because of that.
Compared to other means of energizing friends, Zealot is among those that normally require the most action on the player's part in order to be utilized. This is because of how it will likely be the player who will be killing most Enemies in order to trigger this Item's ability. In addition, Zealot is only capable of impacting a single ally at a time rather than multiple. These two attributes can make it inferior to other means of energizing friends. However, Zealot is one of the few ally energizing Items that can be used outside of the player's Farm. Furthermore, Zealot's ability pairs well with the fact that the majority of the time the player spends outside their Farm will likely be spent clearing Camps. Due to that it can be more valuable for followers that leave the player's Farm, including Drones and certain Spouses. This fact relies on whether or not the player has any of such followers however. Because of this, Zealot is situational on the player's build and may not be the strongest means of energizing their allies, and as such may make other energizing Items more valuable.
