It comes up every week though - if someone missed it they could try again next week, and the week after...if they wanted it bad enough they could surely get it within a few tries. However, I still question the value of it. In those same few weeks you could probably build a gold+3 tyrant brand for less than 85k by saving up some Hyper/Super/Regular Potions as well as utilizing the weekly 2x rewards period in El Dorado.

85k is very well worth it. I could imagine it going for like 200k jewels, because you must not forget the daily struggle of getting the actual brand shards. About the secret vault: it refreshes every so often within its appearance. During the appearance, jewels spent will only and solely account for that particular appearance of the secret vault. After 4 refreshes of the secret vault within that appearance, if you missed your chance to get the tyrants brand, your jewels spent will be lost forever as after that appearance, it will simply forget all the jewels you spent. It's for this particular reason that I do not count on anything which resides in the secret vault.

Dragoneyr - You're absolutely correct. It didn't occur to me at all that if you missed it one week you would have to spend *another* 85k jewels to try the next week...huge risk. However, I still question whether it's worth 85k. Mine is at gold +1 and I just need 30 more shards to go to gold +2 (already upgraded and all part slots filled).Just obtain and save up potions and wait for X2 rewards in El Dorado and I'm convinced you could build it for way less than 85k with a bit of patience - less than 2 months most likely.

The problem to me is often the experience cost. I have 2 gold thunder blades of level 100 sitting around, just being there. They costed 30k each at what I remember to be Lords gone wild event. So I definitely wanted these blades. Especially because they fit my layout and because they are even more useful in Battle Royale
