• Pretty much any event you can do multiple times every day,
  you can join infinity times, BUT!
  Once your reward tries runs out, you won't get any more rewards,
  but you can still do it without getting rewards, like helping a player/friend,
  or just trying it, to train on some tactics. :victory:
