Kingdom Events typically pit two Kingdoms against each other for establishing the champion.
When time expires on the event and one kingdom wins, the game will distribute Gold Reward Temples throughout the winning Kingdom.
These Gold Reward Temples start at Level 1 and progress to Level 6.
Typical strategy should be employed for all events, by attempting to wait for a couple of event types to line up.
When a Solo Event and a Kingdom Event award points for Training Troops, then any troops trained count for both events.
