Hero Quests

Hero Quests are ten step quests in Plants vs. Zombies Heroes, added in the 1.6.27 update. They give various useful rewards including gems, sparks, new cards and even Premium Packs for designed for certain heroes. Each hero has their own unique set of Hero Quests.

In order to do a hero's Hero Quests, the player must complete it when playing with the hero the quest is tied to. For example, to do Professor Brainstorm's quest about playing Science zombies, the player has to play as Professor Brainstorm and do the task instead of another hero.

To complete a Hero Quest, the player must complete 10 different tasks. The first task always involves playing the hero's Signature Superpower, the fourth tasks involves crafting a specific uncommon card, the eighth tasks involve crafting a specified rare card, and the final task involves winning 3 Multiplayer matches. The rest of the tasks vary depending on the hero.
