Event Content[]
Event Materials[]
While the event was live, rewards for event-specific, normal and battle quests at quest level 4 and above included red hero capes, radioactive spiders, and chemical jars, Call of Heroes event materials that could be used to craft hero eggs and plushies and acquire new guild leader items. These materials could also be purchased as microtransactions in the Event Shop.
| Bundle | Cost | VIP XP |
|---|---|---|
| 2000 of each Call of Heroes material | $14.99 USD | +750 |
| Event Pack: 1000 of each Call of Heroes material, 300 gems and Stormcloud |

The quest selection screen included a materials boost button offering the option to watch an ad and get double event materials from quest rewards for 30 minutes.
