Events in Idle Heroes are recurring (although sometimes there are one-off activities or events) where you have to complete certain actions in order to earn decent rewards of loot and goodies. To see what events are currently available you just need to click the hourglass icon called 'Limit Events'. You will find that most of the events in this list will be time-limited and only accessible for a week. They break down as following:
The Summon Events revolve around claiming prizes for summoning high-level heroes. These will be the first type of events you will encounter.
Summon Prizes
Summon Prizes is basically summoning heroes unsing Summon Scrolls where each heroic summon will earn you 1 point up to a total of 550 points. This event gives you the opportunity to pick up powerful weapons, armour, and other items with the top prize currently being a 5-star hero. Note: You cannot use Basic Summon Scrolls or Hearts in this event.
Prophet Summon Event
Prophet summon is basically the same as Summon Prizes but it replaces Heroic Summon Scrolls for Prophet Orbs. To claim all the rewards, which is a combination of rare heroes, hero shards and a huge amount of gold you need 120 Prophet Orbs.
Heroic Miracle
This event is similar to the Summon Prizes event except that it focuses on summoning a set number of 5-star heroes from each faction instead of random heroes. If you complete one of these objectives you will be rewarded with a couple of Prophet Orbs and orange level equipment. Completing all 6 objectives (one for each faction) will reward you with a high-level 5-star hero.
The following events don't revolve around Summon Scrolls and Prophet Orbs and you will still be able to get great rewards from them.
Casino Prizes
In this event you must spin a wheel of fortune, each spin grants you 1 event point and to be eligible for all the rewards you will need a total of 600 points. Each spin you take sets you back 1 Casino Chip. Note: This event is only for the Common Casino, so using Super Chips in the Super Casino does not count towards the 600 points.
