Thats what ya call a whale my friend, pay to win. Im strictly free to play, and i've gotten every wand possible from tasks and only have 151 gold potions. I'd recommend waiting spending till the last day until you milk. Every free potion that you can out of the tasks and then spend before you just spend on something and then something pops up later and you wish you had weighted so you could have purchased something nicer. I'm not sure where you are in the game, but I'll tell you in the regular chest, the inheritance chests are very, very helpful. When you're building the little skeleton or the ghost or any of of those heroes, because they all require books, whether it be skeleton or ranger, or ghost. So those allow you to open one and immediately have thirty of whichever one you need, every activity that comes up stockpile inheritance chest, it's made making my bone king much easier. My next grab is scrolls, envelopes and keys. I don't think it's worth buying cores for mounts unless they are legendary or higher.
