Epic Energy
Epic Energy regenerates at a rate of 1 every 30 minutes, to a total of 10 after 5 hours. The value can end up above 10 through the Epic Energy dropped by the Epic Boss or by buying it with gems, but at that moment regeneration stops until it drops below 10 again. The 2 hour period that an Epic Boss is active, gives enough time for 3 Epic Energy to regenerate.

Arena Energy
Arena Energy regenerates at a rate of 1 every 15 minutes, to a total of 5 after 75 minutes. The value can end up above 5 by buying it with gems, bat at that moment regeneration stops until it drops below 5 again.

Friends Hired
The Frieds Hired list is cleared 23 hours after you hired the first friend. This fact can be used so that the list clears in the middle of an Epic Boss' 2 hour availability, so for part 1 of the fight friends 9 and 10 of that "day" can be used and for part 2 friends 1 and 2 of the next "day" can be used.

Friend Battles
Each of the friends in the Friend Battle list reset 23 hours after you battled that friend.

Health Regeneration
The health of your champion and knights regenerates at the rate of 1 health every 20 seconds, which translates to 3 health per minute or 180 health per hour. Since leveling up adds to your health, the higher level you are, the longer it takes to regenerate from 0 to 100% health.
