Getting the maximum amount of XP and EP from your Dazza/Carissa (dragon)
By following the simple procedure below, you can increase the XP/EP earned by up to 92% when devouring dragons of the same faction.
 * 1) Have your second highest level dragon devour your highest level dragon.  Do not combine dragons of different names, factions, or rarities.
 * 2) Have your second highest level dragon devour your highest level dragon (the one you created in the previous step.
 * 3) Repeat step 2 until your dragon reaches tier 4.  This is the optimum dragon level and devouring any further will reduce the EP you gain.
