I've done everything I can do except finish the white defense gem. I even found an extra great white attack gem shard. But, can't seem to find the last white defense shard. Have literally combed every area with a large bell w/o any luck. Starting to wonder if the extra white attack gem shard was meant to be a defense gem shard and it's a mistake by the developer. If anyone has been able to find the white defense shard, please reply to me and let me know, preferably where too. At this point, I'm considering it impossible to complete though as the only other explanation is that there is a hidden area so out of reach that not even the large bell can detect it.
