I have been trying to do the achievement to get all wands in my inventory, but the max I have got was 9 because I have broken all of the blocks. My suggestion is to make getting a wand that u already have impossible. I have been getting 3/4 wands twice and in the end when I have broken all blocks I will have around 5 wands that I have twice but still be missing 2 or 3 more. Either make the chance to get the same wand more than once when you already have it in your inventory impossible or make the maps have more lucky blocks.
Thanks!
Thanks!
