Today there will be some updates for the Artisan Village/Tree of Wisdom:

• We will have new Bahama Spa runes for you - these will give you 3 packs of extra elixirs and 5 sets of boost for Bahami Bar skillpoints.
• Three new florist recipes will be available.
  
  
  
  
• From today, when the Moonlight Mania Event is not running, it will no longer be possible to buy spooky crops with BBs to make the spooky recipes in the Artisan Village. It is only possible to use crops already in the barn.
