In the past there were Diamond, Soccer, Infinity, Achilles, Passion dragons were the recommended fighters. Now we have Egyptian, Flower, Elemental, Olympus, Gemstone, Royal, Spooky, Zodiac, Dark, Fey, Arcane etc, etc,

How do all of these other dragons types compare with the ADIPS dragons? I've seen the term 2nd Level dragons - what does this mean?
