In the morphing tent in the Circus Maximus, you can create a new egg by morphing two Adult or higher-rank pets together. You can morph two of your own pets or you can pair with somebody else. Morphing costs gold and begins a timer – you can only morph every so often. If you don’t want to wait, you can purchase an Alhazred’s Elixir in the Crown Shop to reset your timer to zero. Your timer is displayed in the lower left corner of the screen. Mouse over the egg icon to see the time remaining.
The pet produced by morphing has a chance to inherit the appearance, powers, talents, and maximum stats of either creator pet. In special circumstances your new pet may be completely different based on the ones used to morph. Your new pet is more likely to inherit desired traits – talents, powers, and maximum stats – if the creator pets are trained and leveled up.
