Did I make a mistake leveling Boon of the Hoarder to 25?

Thanks, so you are keeping boon at 24 then?

Well, I do... Anyway you can "hide" your level 25+ gems in the inventory of a another character and then that chick at the end of Greater Rifts will give you a brand new one. No need to go to the Vault again. At least it worked that way some patches ago.
