You’re not bothering! Don’t worry!
With the sagas, you can only run one episode a day per character to get a box (Unless you have yet to complete the episode ever on a character.)
With this, if you have multiple characters on one account. (Say you started as a Human, you get a free Elf card and free Giant card.) You would have 3 characters you can run the sagas on.(You might also have more, or less, depending what race you chose, or if you bought extra character cards.)
Either way. Each character can run ONE Saga episode a day.
Let’s say you have just one character. You can run episode 7 on that character once a real life day. You do not open the boxes you get from beating the episode until it hits the weekend (Saturday or Sunday.) This ensures you get the 30k bonus for each box you open, along with either a saga coupon or weapon/coin.
Should you do this, for one character, you get 210k for that character for those 7 days you ran episode 7. (Don’t forget to NPC the big gold pouches too!)
If you open the boxes any other day other than Thursday(EP7 bonus), Saturday, or Sunday, you will not get the 30k Bonus.
I hope I answered your questions!
