I currently have a hero book in my clan castle. I am about to complete the golem challenge which will reward me a hero book. What will happen if I complete the challenge with no spot for the book?

If it is completing an event, the book will be added to your clan castle(Town Hall in the new update). Rewards for events stack so that you can have more than the maximum number! I currently have 9 power potions; the maximum is 5; 4 were rewards for completing challenges during events

If it is part of a clan game, it will not stack and you will not be able to choose it as a reward.


You can always have those rewards from events as the players have earned it by completing event so supercell does not take it away from us. I had 6 training potions and two book of fighting so no need to worry.


Your second will be useless as it is clearly observed that Treasury have only 1 storage place for the Hero Book. So before completing challenge reward, make sure you have empty room for Hero Book.

    Thanks, I though so, but I wondered if it would give me a chance to use it/ sell it or if it would just poofff?! Apr 8, 2018 at 1:03
  • Had to downvote because this doesn't clearly answer the OP's question, "What will happen ..." Apr 25, 2018 at 23:56
  • Ohh Dear Lord @NickRolando, It clearly says "Your Second Will Be Useless". Don't you read? Apr 27, 2018 at 22:13
  • Lol, so you're saying you'll get the 2nd book but it will be useless? That's blatantly false. Apr 27, 2018 at 22:55
  • Your answer lacks much detail. Will he be forced to claim the prize immediately, and the extra book goes poof? Or can he choose to claim it at a later time after he uses the one he has? "Your second will be useless" is not only false but vague. Apr 27, 2018 at 22:58
