I bought the spellbound bloom in the firsts days, after seeing the few drops of dew, and to take advantage of the "discount" of 60 gems.
As many others I'm sure that in future we will have a goal with the visit to a level 6 building. But... Which?
With more than 20 different buildings difficult choice.
By the moment I'm doing spellbound blocks and beams, I've two of each and continue doing more. By now, I wait to upgrade one building until I've more beams and blocks, or the goal when these are necessary.
