Have you had a rough day out digging with your Dragons and they are about to fall asleep. Never fear Mystical Creatures has a product for that.
The amazing Mystical Electrum Essence can increase your Dragons Energy by 25%, which is amazing and will give you more time to dig or allow them to breed if they are close to giving you a new Egg.
Sadly you can only use this boost once per 24 hours so make it count when you need it.
